Aluminum Nitride Overview
Aluminum nitride (Aluminum Nitride) is a non-toxic crystal that belongs to the atomic system of hexagonal nitride.
How to make aluminum nitride
The carbothermic reduction technique involves heat treating aluminum oxide, or aluminum hydroxide between 1400-1800degC with nitrogen or ammonia and carbon as a reductant.
What are the uses of aluminum nitride
In the present, most research is aimed at developing a light-emitting device based on a semiconductor (gallium oxide or alloy aluminum gallium oxide) that operates under ultraviolet light and has a wavelength of 250 nanometers. Aluminum nitride has many uses in optoelectronics. It is used as a dielectric in optical storage interfaces, electronic substrates, chip carriers with high thermal conductivity and even for military purposes.
A surface acoustic-wave detector also uses epitaxial stretching due to the piezoelectric effects of aluminum Nitride. The detector will then be mounted on the silicon wafer. The thin film can only be manufactured reliably in very few places.
It has good thermal conductivity and a low expansion coefficient. It can also be used to make heat exchangers for structural components that are exposed to high temperatures.
Aluminum nitride can resist corrosion to iron, aluminum, and other metals. It can also be used as a casting mold for melting metals including Al, Cu Ag and Pb.

Vacuum packaging is used for powder packaging. There are 4 general specifications: 100g, 500g, 1kg/bag and 25kg/barrel. It is possible to package it according to your specific requirements.
Rapid inactivation SARS-CoV-2 using silicon nitride and copper and aluminum nitride
Silicon nitride has successfully inactivated SARS CoV-2. The surface release of disinfectants that contain nitrogen is the mechanism. Copper and aluminum nitride are both effective at inactivating viruses. Although the first compound affects the cells, the second compound has a toxic effect. It is necessary to conduct further research to confirm these findings, and to investigate whether silicon-nitride may be incorporated in personal protective gear and on surfaces that are frequently touched as a way to inhibit virus persistence and disease spread.
China’s sensor industry will benefit from aluminum nitride ceramic substrate
In microelectronics the smaller the size of an integrated circuit, the higher the integration, faster the speed of running, and better the performance. The Internet of Things is also deployed when the sensor size of a system is smaller. It is easier to use and performs better. The hardware requirements for this are also higher. The sensor chip is at the core. There are currently only a handful of large-scale manufacturers in China. The main chip materials are FR-4 substrates, and aluminum substrates. Aluminum nitride-ceramic substrates were used extensively in developed countries. Aluminum nitride Ceramic Substrates have improved thermal conductivity and insulation, as well as better stability. They are the prized possession of top-notch sensor manufacturers.
