Source: https://www.innovacera.com/news/aluminium-nitride-ceramic.html Aluminium nitride has a high heat transfer ability so that aluminium nitride is widely used in microelectronics. Unlike beryllium oxide, aluminium nitride is non-toxic. Aluminium nitride is treated with metal and can replace alumina and beryllium oxide for a large number of electronic instruments. (1) Refractory materials. Aluminium nitride is not only resistant to high temperature, corrosion, alloys and metals such as aluminium and iron, but also non-wetting with silver, copper, aluminium, lead, etc., and can be used to make refractory materials or coatings for crucibles as surface protection material. It can also be made into structural materials such as casting moulds and crucibles. (2) Electronic substrate material. Aluminium nitride ceramics are widely used in multi-chip modules in military fields, microwave power amplifiers, and laser diode carriers, LED heat sink substrates and high-temperature semiconductor ...

Source: https://www.innovacera.com/news/aluminium-nitride.html 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 indus...
