Market analysis of China aluminium nitride industry
Aluminium nitride has become an important precision ceramic material because of its high thermal conductivity, high insulation resistance coefficient, excellent mechanical strength, and thermal shock resistance.
It is the ideal heat dissipation and packaging material for next-generation large-scale integrated circuits, semiconductor module circuits, and high-power devices.
Although the production capacity of aluminium nitride in China has reached a certain scale, the quality of aluminium nitride powder is not high. Some enterprises claim that the production capacity is put into production, but there is no actual output or low output.
With more domestic aluminium nitride powder projects put into operation and capacity utilisation increasing, it is expected that by 2020, China’s aluminium nitride powder output will increase to about 1,000 tons.
In recent years, with the rapid development of China’s electronics industry, the demand for aluminium nitride market has grown rapidly, with an average annual growth rate of 50%.
It is expected that the demand for aluminium nitride powder in China will maintain a growth rate of more than 30% in the next few years.
By 2020, China’s aluminium nitride market capacity is expected to reach 3,000 tons.
Boiler igniter (Hot air gun) Installation Precautions
Classification of hot air guns: hot air gun with built-in fan; air gun without the fan.
The drypoint can reach 1200 ° C.
Using high-performance silicon nitride ceramics as the substrate, high-temperature mechanical strength, strong thermal shock resistance, acid and alkali corrosion resistance, both excellent insulation properties and good thermal conductivity, coupled with our company’s proprietary formula and heat Pressure manufacturing technology.
Hot air gun installation precautions:
- When installing the hot air gun with silicon nitride heater, the outlet should be inclined downward by 15°.
- The nozzle of the hot air gun cannot pass over the wall of the furnace (to ensure that the heating plate radiate to avoid burning the heating plate);
- When working, the distance between the nozzle and the particle in the furnace does not exceed 5CM. A ball valve adjusts the air inlet of the hot air gun without a motor. (Can improve ignition efficiency);
- The recommended control system allows the heater to work for 5 seconds before the blast enables the hot air to blow out immediately. (Effective ignition particles to avoid particles in the incomplete ignition of smoke)
- Do not touch the boiler box and the metal casing wall when the heating plate is working (it can effectively avoid power failure and trip protection).

INNOVACERA® ceramic laser reflectors
INNOVACERA® ceramic laser reflectors are high-efficiency diffuse reflectors. The perfect diffuse reflection and high reflection efficiency are effectively exploited in laser systems in the 500 nm to 1200 nm spectral range.
INNOVACERA® ceramic reflector is approximately 15-18% porous and virtually no absorption losses. It is suitable for dry cavity laser applications such as low energy air-cooled systems and higher energy laser systems
The curve shown below illustrates the reflectivity of the INNOVACERA® ceramic reflector.
Ceramic laser cavity reflectors reduce and eliminate many of the shortcomings of PTFE polymer reflectors, polished metal specular reflectors, and packed powder diffuse reflectors. Here are some advantages of ceramic reflectors.
– Ceramic material is strong to resist breakage if a flashlamp explodes
– Glazed surfaces are corrosion resistant, allowing direct contact with coolants
– There is no plating to flake off like specular metal reflectors
– High electrical resistivity
– Good thermal conductivity
– No pollution

Spark plugs and ceramics – an unexpected combination of life
Spark plugs are an integral part of the motorization era. Everyone travels every day, and there are countless small spark plugs that support this vast modern society. Today, I will tell you about the application and role of ceramic products in spark plugs. The unexpected combination of ceramic and spark plugs is practical, economical, and efficient.

A spark plug is an integral part of a gasoline engine ignition system that introduces a high voltage current into a cylinder to create an electrical spark to ignite a combustible gas mixture. The main components are the wiring nut, the insulator, the terminal screw, the centre electrode, the side electrode, and the outer casing, wherein the side electrodes are welded to the outer casing. The ceramic material acts as an insulator in the spark plug.

The surface of the ceramic part as an insulator has a plurality of groove-like corrugations for preventing arc generation, that is, preventing sparking between the terminal nut and the main metal (because the terminal nut and the main metal are in ignition) High voltage electricity is generated and the high voltage electricity attempts to slip along the surface of the insulator. In order to block high voltage electricity, a layer of ditch is provided.
Insulation, heat resistance, and thermal conductivity are characteristics of alumina ceramic materials.
Alumina ceramic is a ceramic material with α-Al2O3 as the main phase. The alumina content of the alumina ceramics used in engineering is usually between 75% and 99.9%. It is usually classified according to the content of Al2O3 in the composition. Al2O3 porcelain is widely used, and its properties depend on the content of Al2O3. Usage is also different.

High mechanical strength
The bending strength of Al2O3 porcelain sintered products can reach 250MPa, and the hot pressing products can reach 500MPa. The purer the Al2O3 component, the higher the strength. The strength can be maintained to 900℃ at high temperatures.
High resistivity and good electrical insulation performance
The normal temperature resistivity is 1015 Ω·cm and the dielectric strength is 15 kV/mm. With its insulation and strength, it can be used to make substrates, sockets, spark plugs and circuit casings.
High hardness
Mohs hardness is 9, plus excellent wear resistance.
What’s more advantage of alumina? High melting point and corrosion resistance; excellent chemical stability; optical properties and ionic conductivity.

After the above introduction, I believe that the reader has a preliminary understanding of the performance of alumina ceramics. Alumina ceramics are ideal for spark plugs due to their high electrical resistivity and excellent electrical insulation properties. Small body, full of energy. Small ceramic parts drive our society and power our lives.
MCH Heater VS PTC Heater
What’s the difference between MCH heater and PTC heater?
MCH heater is short for metal-ceramic heater. It is a new type of heater which is highly efficient and more environmental, energy-saving. It can save to save more than 20% to 30% power effect compare to the PTC heater. It has excellent insulation performance. MCH heater widely used in all kinds of industries. Such as flat hair iron, soldering iron, soldering station, water heating, pellet boiler, e-cig, 3D printer heater, etc.
MCH heater is rapid heating. It can reach 900 degrees in 50 seconds.
PTC heater is short for positive temperature coefficient and widely used for their enable safe, powerful, and energy-efficient heat transfer. The application of power on the PTC can work with a robust safety system, and you will never worry about the overheating even you forgot to switch off your use after work.
