Solid-state Yellow Glazed Alumina Ceramic Concentrating Cavity / Laser Reflector

The yellow-glazed ceramic concentrating cavity exhibits high reflectivity in the main absorption band of the solid-state laser, and at the same time exhibits the function of reducing the reflectivity in the ineffective absorption band. In contrast, the diffuse reflective ceramic condenser cavity has high reflectivity in the non-absorptive ultraviolet band of the laser crystal, but it cannot effectively filter out the ultraviolet light that produces a harmful color center to the laser crystal. The highly reflective, UV-absorbing ceramic glaze can obviously improve the shortcomings of ordinary ceramic condenser cavities. It has the characteristics of strong laser radiation resistance, high insulation, corrosion resistance, easy cleaning, and UV absorption.

Ceramic Plungers – The Best Choice For Industrial Pumps

In the process of material transportation in chemical engineering, metal smelting, mining, and other industries, the delivery pump often needs to be subjected to the impact of the slurry containing solid particles, the erosion of corrosive processes, and the impact of high-temperature fluids. These working conditions are potentially destructive. , It is easy to have a major impact on the delivery pump, and even affect the normal operation of the delivery pump or cause medium pollution to the transmission medium.

In order to ensure the stable progress of the process in extreme working conditions, the selection of pump components, such as pump plungers, is very important. The plunger reciprocates in the plunger cylinder for a long time. They must have high hardness, high melting point, low wear, acid, and alkali corrosion resistance, etc., otherwise, they cannot be supported.

Ceramic Plungers – The Best Choice For Industrial Pumps

Advanced ceramics that can maintain these characteristics at high temperatures are quite suitable choices. The ceramic plungers are made of high-performance technical ceramic material, which has the properties of high hardness, wear resistance, high-temperature resistance, and corrosion resistance. The working surface of ceramic plungers is processed with a “mirror” surface and has a good self-lubricating effect. Tests have proved that the high wear resistance of the ceramic plunger is much higher than that of the traditional metal plunger, and it is an ideal substitute for the metal plunger, which greatly extends the service life of related parts.

Advanced Ceramics Is The Most Potential Development In New Materials Field

According to the preparation technology and application field of ceramics, ceramics can be divided into traditional ceramic materials and advanced ceramic materials. Advanced ceramics have gradually become an important part of new materials.

Advanced ceramics: according to chemical composition can be divided into oxide ceramics, nitride ceramics, carbide ceramics, boride ceramics, silicide ceramics, fluoride ceramics, sulfide ceramics, and so on. According to its properties and uses, it can be divided into two categories: energy ceramics and structural ceramics. Functional ceramics are mainly based on the special functions of materials, with electrical properties, magnetic properties, biological properties, thermal sensitivity, optical properties, and other characteristics, mainly including insulating and dielectric ceramics, ferroelectric ceramics, piezoelectric ceramics, semiconductor, and sensitive ceramics, etc. Structural ceramics are mainly based on the mechanical and structural uses of materials, with high strength, high hardness, high-temperature resistance, corrosion resistance, oxidation resistance, and other characteristics.

Advanced Ceramics Is The Most Potential Development In New Materials Field

Structural ceramics with their excellent mechanical and thermal properties become an important branch of ceramic materials, accounting for about 30% of the whole ceramic market. In nearly 20 years, the national major projects and cutting-edge technology in ceramic material and its preparation technology is also put forward higher demands and challenges, such as aerospace rocket liquid hydrogen in liquid oxygen turbine pump use of silicon nitride ceramic bearings under the condition of low-temperature extremes no-slip condition at high speed, requirements at the beginning of the ceramic bearing high strength, good, wear resistance, surface processing of high precision; The large size ceramic sealing ring used in the main pump of nuclear power plant needs long service life and high reliability. In particular, the silicon carbide ceramic reflector used in the ground monitoring of the earth satellite shooting targets, in addition to high elastic modulus, low thermal expansion coefficient, and lightweight, requires high precision ultra-mirror and large size. This is a challenge to the molding technology, sintering technology, and processing technology of large-size structure ceramic materials. In optical communication, the inner hole of the optical fiber connector is 125 microns, and it requires a very high surface finish, dimensional accuracy, and concentricity. So Structural ceramics is the most promising quality material in an extreme environment.

For the oxide ceramics, nitride ceramics in structural ceramics, below is their feature:

Alumina ceramics: the earliest and most widely used structural ceramics

Zirconia ceramics: high-performance structural ceramics, toughening is the key to preparation

Beryllium oxide ceramics: oxide ceramics with the highest thermal conductivity,

Silicon nitride ceramics: one of the materials with the best comprehensive properties in advanced ceramics

Aluminum nitride ceramics: ideal structural material for microelectronics industry circuit board and packaging

Boron nitride ceramics: soft ceramics in ceramic materials, good machinability

Advantages Of AlN Ceramic Materials Used As Copper Clad Substrate Materials

At present, high-performance aluminum nitride ceramic plates are used as thermal conductive substrates in advanced packaging processes, and copper is directly bonded on aluminum nitride to further design circuits, surface mount transistors, and power diodes. Due to its good thermal and electrical properties, AlN has gradually become the preferred material for this type of substrate design and can be used as insulating substrates for high-power devices, heat dissipation substrates for VLSI and packaging substrates, etc.

Advantages Of AlN Ceramic Materials Used As Copper Clad Substrate Materials

Aluminum nitride copper-clad laminate has the thermal conductivity and mechanical strength of aluminum nitride, as well as the thermal conductivity and electrical conductivity of copper, so it has great application potential in the aerospace field. In addition, the “copper-aluminum nitride-copper” sandwich structure can play a key role in the modularization and integration of electronic systems, serving as mechanical support, electrical isolation, and heat dissipation paths for power modules. It is worth noting that in the application of aluminum nitride copper clad laminate, the interface bonding between AlN and Cu is very important, and the interface phase determines the bonding force between the ceramic and the metal copper layer. The conventional preparation process of aluminum nitride copper-clad laminate includes the hot pressing method and the direct copper cladding method (DBC).

The hot pressing method requires sputtering a metal layer on the surface of AlN by magnetron sputtering and then introducing copper sheets for hot pressing. The DBC method requires pre-oxidation of AlN ceramics and Cu sheets, and then heat treatment to bond. The peel strength of the substrate prepared by the DBC method is about 4 times that of the hot pressing method, and Cu and AlN can form a stronger bonding force, which has better application prospects in the aerospace field with harsh service environments.

Beryllia Ceramic BeO Metallization

The thermal conductivity of BeO ceramics is very high, which is comparable to that of some metal materials; it also has the advantages of high-temperature resistance, high-pressure resistance, high strength, and low dielectric loss, which meets the requirements of power devices for insulation performance. However, BeO powder is a highly toxic substance, which can cause serious harm to the human body and the environment. This fatal shortcoming greatly limits the production and application of BeO ceramic substrates in the industrial field

Beryllia Ceramic BeO Metallization

The most commonly used metallization method for BeO ceramics is the molybdenum-manganese method. The method is to apply a paste-like mixture of pure metal powder (Mo, Mn) and metal oxides on the ceramic surface, and then heat it at a high temperature in a furnace to form a metal layer. Adding 10%~25%Mn to Mo powder is to improve the combination of metal coating and ceramics.

However, the molybdenum-manganese method also has certain limitations on the metallization of BeO ceramics. The thermal conductivity of BeO ceramics can reach more than 300W/(m•K), but the thermal conductivity of molybdenum is only 146W/(m•K). It is not conducive to the high heat dissipation characteristics of BeO ceramics. In order to improve this drawback, the tungsten-manganese method was developed on the basis of the molybdenum-manganese method. The thermal conductivity of metal tungsten is higher than that of metal molybdenum, and the electrical resistivity of tungsten is also lower than that of metal molybdenum. Therefore, the tungsten-manganese method can not only improve the heat dissipation efficiency of the overall structure but also help to improve the electrical conductivity of the metallization layer.

Microporous Ceramic Technology

Overview of Porous Ceramics

When it comes to microporous ceramics, the porous ceramics must be explained first.Porous ceramic is a new type of ceramic material, also known as porous functional ceramic. It is a ceramic material with a large number of open or closed pores. It is made by calcining at high temperatures, and many porous structures are made during the sintering process.

Classification of Porous Ceramics

Porous ceramics can be classified by dimension, phase composition, and pore structure (pore size, pore morphology, and pore connectivity), among others.The pore structure can be divided into uniform pore structure and non-uniform pore structure.According to the pore-forming method and pore structure, it can be divided intothe intergranular ceramic sintered body (ie, microporous ceramics), foamed ceramics, and honeycomb ceramics.

According to the size of the pore size, Microporous ceramics is divided into as below:

Type	Pore size
Coarse pores	>500μm
Large pores	100~500μm
Micro pores	1~100μm
Nanopores	＜1um

Definition of Microporous Ceramics

Microporous ceramics have a uniform pore structure, which is a new type of functional structural ceramics. The micropores are very small and are generally micron or submicron, which is invisible to the naked eye. However, microporous ceramics are visible in daily life, such as the ceramic filter elements used in water purifiers and the atomizing cores in electronic cigarettes, etc.

Fabrication of Microporous Ceramics

Porous ceramic pore-forming principles and methods mainly include as below.

Particle accumulation→ Addition of pore agents→low-temperature underfired →mechanical processing into pores.

Asa new type of inorganic non-metallic filter material, microporous ceramics are made of aggregate particles mixed with a certain amount of binder, and then fired at high temperature after the pore-forming agent.

Quartz sand, corundum, alumina (Al2O3), silicon carbide (SiC), mullite (2Al2O3-3SiO2), and ceramic particles are used as aggregates. Generally, aggregates are required to have high strength, heat resistance, corrosion resistance, close to spherical shape (easy to construct into filtration conditions), easy granulation within the specified particle size range, and good affinity with binders. If the aggregate base material and particle size are the same, and other conditions are the same, the pore size, porosity, air permeability and other indicators can achieve the ideal purpose.

Application of Microporous Ceramics

Microporous ceramics have the advantages of adsorption, gas permeability, corrosion resistance, environmental compatibility, biocompatibility, surface structure with unique physical and chemical properties, etc.

As gas-liquid filtration, purification and separation, gas distribution, sound absorption, and shock absorption, heat exchanger materials and chemical fillers, bioceramics and catalyst carriers, adsorbents, biological implant materials, special wall materials, artificially manufactured organs, and refractory materials, sensor materials, etc.

Silicon carbide porous ceramics have been widely used in environmental protection, energy saving, aerospace, chemical, petroleum, smelting, food, pharmaceutical, biological, medical, aquaculture, and other industries, greatly improving the product quality and market competitiveness of these industries.
