Alumina Laser Ceramic 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.

What are the defects on the surface of alumina ceramics?

Alumina ceramics is a kind of ceramic material with Al2O3 as the main raw material. It has many advantages, such as high mechanical strength, high hardness, and low dielectric loss at high frequencies, so it is widely used in the fields of electronics, electrical appliances, machinery, textiles, and aerospace. But do you know what is its defect?

Alumina ceramics have a series of production processes. During the process, materials will come into contact with machinery, equipment, tools, utensils, and the environment. Therefore, there are many factors that cause pollution and quality problems in ceramic parts. In general, the common quality problems related to color after sintering of alumina ceramics are:

(1) There are spots on the surface, such as black spots, brown spots, and red spots;

(2) There are plaques on the surface, such as dark plaques, black plaques, bright plaques, etc.;

(3) Ceramic parts have chromatic aberration, such as overall yellowing or graying;

Innovacera has extensive experience in the manufacture of alumina ceramics and we have a lot of solutions to avoid the above issue.

What Is Zirconium Oxide Used For?

Zirconium Oxide (or Zirconia) products demonstrate good mechanical properties and stability at elevated temperatures. Zirconium oxides also have excellent chemical inertness and are resistant to corrosion. All of these properties make zirconium oxide ideal for use in refractory products, ceramics materials, and electronic applications.

Zirconium Oxide is also a highly versatile material when combined with other elements. The addition of yttrium oxide unlocks the tetragonal polymorph and further enhances the mechanical properties and forms materials suitable for advanced ceramic applications. These include cutting tools, abrasives, milling media and even medical implants including dental prosthetics. Further addition of yttrium oxide yields the cubic polymorph and can lead to function ceramics which can conduct oxygen ions. Applications include materials for fuel cells, used in oxygen sensors, and cubic zirconia for jewelry. PZT, Glass, bone cement.

Zirconium Oxide doped with magnesium oxide can produce partially stabilized materials that offer thermal resistance and tough materials, ideal for use in refractories.

Zirconium Oxide for electronic applications typically combines zirconia with other metal oxides such as Lead and Titanium oxide to form Lead Zirconium Titanate (PZT). PZT’s are used in ultrasound devices, guidance systems, and sensors. Zirconium oxide can also be used in Solid Oxide Fuel Cells either as zirconia or in yttria-stabilized form.

Refractories

Zirconium Oxide’s excellent thermal resistance and mechanical properties at elevated temperatures make it the perfect material for refractory applications.

Advanced ceramics

Yttrium-doped zirconium oxide provides advanced mechanical properties for use in cutting tools, abrasives, and milling media due to its high wear resistance.

Medical products

Zirconium oxide can be used as a radiopacifier in surgical cement due to its low solubility and biocompatibility. Dental implants can also be manufactured from Zirconium Oxide by carefully controlling the level of yttria added to fine-tune mechanical strength vs. optical properties.

Glass-ceramics

Cubic zirconia is a fully stabilized Zirconium oxide and can be used for jewelry, however, due to zirconia’s excellent refractive index, it can be used in optical glass formulations to improve its properties.

Electronics

Zirconium Oxide, whether on its own or combined with dopants, finds itself in electronic applications, such as PZTs and fuel cells.

INNOVACERA offers a wide range of Zirconium Oxides and Yttria Stabilized Zirconium Oxides.
We’d love to hear about your applications and discuss how our materials can offer you a solution.

What Factors Are To Affect The Metallization Of Ceramics?

1. Metallization formula.

This is the premise of realizing ceramic metallization, and its formula needs to be carefully and scientifically designed.

2. Metallization sintering temperature and holding time.

The metallization temperature can be divided into the following four processes:
1) Ultra-high temperature if the temperature exceeds 1600°C,
2) High temperature at 1450~1600°C,
3) Medium temperature at 1300~1450°C,
4) Low temperature if it is lower than 1300°C.
An appropriate sintering temperature is necessary. If the temperature is too low, the glass phase will not diffuse and migrate. If the temperature is too high, the metallization strength will be poor.

3. The microstructure layer of Metallization.

The metallization process determines the microstructure of the metallization layer, and the microstructure directly affects the final performance of the welded body. To obtain good welding performance, the metallization layer should first be a dense film with high bond strength. If the microstructure of the metalized layer has distinct layers and no continuous brittle metal compounds are observed at any interface, the probability of brittleness and crack propagation will be reduced, and the interface will have fewer cracks, which is beneficial to reduce solder penetration. It shows that the metalized layer has good compactness and relatively high bonding strength.

4. Other factors.

There are still many factors that affect the degree of ceramic metallization that need to be paid factors are to affect the metallization of ceramic[/caption]attention to, such as the influence of powder particle size and reasonable gradation, the powder being too fine, the surface energy being large, and it is easy to form agglomeration, which will affect the smoothness of the coating; if the powder is too coarse, the surface energy decrease, resulting in an increase in the sintering temperature, which affects the sintering quality. In addition, the coating method and the thickness of the coating will also have a great influence on ceramic metallization.

What Are The Factors That Affect The Thermal Conductivity Of AlN Ceramic Substrates?

First of all, let’s overview AlN Ceramics
AlN is a covalently bonded compound with a stable structure and hexagonal wurtzite structure without the existence of other allotypes. Its crystal structure is the AlN4 tetrahedron produced by the disproportionation of aluminum atoms and adjacent nitrogen atoms as the structural unit; the space group is P63mc, which belongs to the hexagonal crystal system.

The main features of aluminum nitride ceramics:
(1) High thermal conductivity, which is 5-10 times that of alumina ceramics;
(2) The thermal expansion coefficient (4.3×10-6/℃) matches the semiconductor silicon material (3.5-4.0×10-6/℃);
(3) Good mechanical properties;
(4) Excellent electrical properties, with extremely high insulation resistance and low dielectric loss;
(5) Multi-layer wiring can be performed to achieve high density and miniaturization of packaging; (6) Non-toxic, good Conducive to environmental protection.

Various factors affecting the thermal conductivity of AlN ceramics
At 300K, the theoretical thermal conductivity of AlN single crystal material is as high as 319W/(m K), but in the actual production process, due to the purity of the material, internal defects (dislocations, pores, impurities, lattice distortion), grain The thermal conductivity is also affected by various factors such as orientation and sintering process, which are often lower than the theoretical value.

In summary:
Selecting the appropriate sintering aids in the composite system can achieve a lower sintering temperature of AlN and effectively purify the grain boundaries, and obtain AlN with higher thermal conductivity.

BN Nozzle for Metal Gas Atomisation

Boron Nitride is oxidation and corrosion-resistant, making it suitable for high-temperature processes such as steel processing and ceramic manufacturing.
Key features:
1. Inert – oxidation resistant up to 850ºC in air, 2000ºC inert atmospheres
2. Resistant to corrosion by most molten metals
3. Non-toxic

BN Nozzle for Metal Gas Atomisation

It is a ceramic with a high melting point; it is tough enough to prevent cracks; it has high thermal shock resistance, and it’s easily machinable. In addition, molten metals cannot ‘wet’ the surface of boron nitride, which means that it is not easily clogged during the atomization process.

Under high vacuum, boron nitride can survive up to 1800 °C. A gas atmosphere can push this even further to 2100 °C. This means that boron nitride will remain solid through the melting of most metals.

Boron nitride has a very low thermal expansion. Together with the high heat conductivity, this ensures that the material has very high shock resistance. It can easily withstand the rapid gradations in temperature inside the atomizer. It does not break or crack under thermal stresses.

It is also highly machinable, allowing us to make small threads, holes, and other finer details with high precision and tolerance. Nozzles made from boron nitride can be easily customized, allowing confined as well as free geometries.

Ceramic Reflectors For Aesthetic Laser & IPL systems

Some Medical/Aesthetic Laser & IPL systems could be fitted with a Ceramic Reflector. Ceramic Reflectors are designed to focus the flash lamp energy produced within the laser cavity/IPL Head towards the Laser Rod/work area in order to achieve maximum output.

As with many components within the cavity of a system, over time the Ceramic Reflectors will lose their reflectivity. Therefore, the overall output energy of the system will reduce. It is highly recommended that in order to maintain the efficiency of the system, these components are replaced on a regular basis.

Innovacera is able to offer all types and sizes of Ceramic Reflectors. For more information get in contact with the team.
