Overview of aluminum nitride Aluminum nitride is an atomic crystal, belonging to diamond-like nitride, hexagonal crystal system, wurtzite crystal structure, non-toxic, white or off-white.
How do you make aluminum nitride?
The synthesis of AlN by the carbothermic reduction method involves the heat treatment of aluminum oxide or aluminum hydroxide at 1400-1800degC under nitrogen or ammonia in the presence of carbon as a reducing agent. What is aluminum nitride used for?
Most research nowadays is developing a light-emitting diode based on semiconductor (gallium nitride or alloy aluminum gallium nitride) and operating in ultraviolet light, and the wavelength of light is 250 nanometers. Aluminum nitride is used in optoelectronic engineering, including as dielectric layer in optical storage interface and electronic substrate, as chip carrier with high thermal conductivity, and for military use.
Due to the characteristics of the piezoelectric effect of aluminum nitride, the epitaxial stretching of aluminum nitride crystals is also used in surface acoustic wave detectors. The detector will be placed on the silicon wafer. There are very few places where these thin films can be reliably manufactured.
The use of aluminum nitride ceramics has a high room temperature and high-temperature strength, small expansion coefficient, and good thermal conductivity. It can be used as a heat exchanger material for high-temperature structural parts.
Using aluminum nitride ceramics can withstand the corrosion of iron, aluminum and other metals and alloys, it can be used as a crucible and casting mold material for melting metals such as Al, Cu, Ag, and Pb.

How to package and transport aluminum nitride powder
P ackage
For powder packaging, vacuum packaging is usually used, and there are four general packaging specifications of 100 g, 500 g, 1 kg/bag, and 25 kg/barrel. Of course, it can also be packaged according to specific requirements.

The rapid inactivation of SARS-CoV-2 by silicon nitride, copper and aluminum nitride
Silicon nitride successfully inactivated SARS-CoV-2. The mechanism of action is surface release mediated by the hydrolysis of nitrogen-containing disinfectants. Both aluminum nitride and copper are also effective for virus inactivation. However, although the former compound affects cells, the latter compound has a cytopathic effect. Further research is needed to verify these findings and investigate whether silicon nitride can be incorporated into personal protective equipment and commonly touched surfaces as a strategy to suppress virus persistence and disease transmission.

Aluminum nitride ceramic substrate will help China's sensor market
In microelectronics, the smaller the feature size of the integrated circuit means the higher the integration of the device, the faster the running speed, and the better the performance. The smaller the size of the sensor in the Internet of Things system also means that the system is deployed. It is more convenient and better in performance. But at the same time, the hardware requirements are even higher. The core of it is the sensor chip. At present, there are few large-scale sensor manufacturers in China, mainly small and medium-sized manufacturers. The chip materials are mainly FR-4 substrates and aluminum substrates. However, in developed countries, aluminum nitride ceramic substrates have been used on a large scale. Aluminum nitride ceramic substrates have better stability, better insulation capacity, and ultra-high thermal conductivity. They have become the jewel in the palm of world-class sensor manufacturers.

Aluminum nitride This material is ideal for packaging a new, highly integrated generation of semiconductor substrates and electronics. Aluminum nitride is also used in crucibles to melt non-ferrous materials and semiconductor materials, such as gallium arenide. They can be used for high temperature insulation parts and thermocouple protection tubes. This inorganic material has a broad range of applications. The substrate material is aluminum nitride
Substrate materials used for electronic packaging must have high electrical resistance, good thermal conductivity and a low dielectric constant. The substrate for packaging should also be able to match silicon wafers thermally, have a high flatness surface, be easy-to-metallize, have a low cost and easy processing. Due to their high thermal conductivity, good high-frequency properties, good insulation properties and stable chemical properties of ceramics, they have become the most widely used substrate materials. Commonly used ceramic substrate materials include beryllium oxide, aluminum oxide, aluminum nitride, etc. Aluminum oxide ceramic substrates have a low thermal conductivity, and their thermal expansion coefficient is not comparable to that of silica. Beryllium dioxide has excellent properties but its powder can cause pronounced effects. Poison, aluminum nitride, ceramics with high thermal conductivity. They also have excellent thermal shock resistance and good mechanical properties, making them the ideal substrate.
Transparent ceramic materials
Transparency of ceramics refers to electromagnetic waves passing through the material within a particular electromagnetic frequency range. If electromagnetic waves within the infrared range can penetrate a sheet of ceramic, then the sheet is infrared-transparent ceramic. Pure aluminum-nitride ceramics, which are transparent and colorless crystals with good optical properties, can be used for heat-resistant coatings on high-temperature optical windows and fairings. Therefore, aluminum nitride The military uses ceramics in a variety of ways.

Applications of Aluminum Nitride in Machinery Industry
Aluminum nitride can be used to make wear-resistant components. Due to its high price, aluminum nitride can only replace severely worn parts. The oxidation and wear resistance of some metal or nonmetal surfaces can be improved by coating them with aluminum nitride. Aluminum nitride coatings can be used for anti-corrosion purposes, including the linings in containers and processing equipment that are corrosive.
Aluminum nitride high-temperature structure material
Aluminum nitride exhibits good corrosion resistance in ceramics both at high and low temperatures. Only at 2450degC will it decompose. As a high-temperature material, it can be used in crucibles and molds. Aluminum nitride can resist dissolution and is not affected by copper, aluminium, silver or other substances. It can be used as a container or high-temperature protection layer, such as thermocouple protective tubes and sintering apparatuses. For high-end semiconductor equipment like aluminum nitride nitride ceramic chuck, corrosive gases are used. Aluminum nitride, which is stable for molten sodium salts like gallium arsenide can be used instead of glass in order to synthesize high-purity semiconductors.
Aluminum Nitride Composite
As a packaging product, the requirement for good heat and thermal dissipation is increasing. The epoxy resin has good mechanical and chemical stability. It is also easy to cure. However, it has a low thermal conductivity. Nano aluminum nitride, a powder with high thermal conductivity, can be added to epoxy resin in order to improve its thermal conductivity.
Titanium Nitride is used to create N/AlN composite materials. Titanium Nitride has excellent properties including high melting temperature, high hardness and electrical and thermal conductivity on the same scale as metal. It also exhibits corrosion resistance. A small amount titanium nitride added to the aluminum nitride matrix. According to conductive-percolation theory, when doping reaches a threshold, a path of conductivity is formed in crystal. This allows the volume resistance of aluminum nitride to be reduced by 24 orders of magnitude. The composite ceramics made from these two materials are also characterized by high hardness, wear resistance, as well as the ability to be used for high-grade materials.
