What is Aluminum Nitride Ceramic?

Aluminum nitride ceramics are ceramics with aluminum nitride (AIN) as the main crystal phase. Aluminum nitride powder has high purity, small particle size and high activity, and is the main raw material for manufacturing high thermal conductivity aluminum nitride ceramic substrates.

Hardness of Aluminum Nitride Ceramics

With the development of science and technology, the application of aluminum nitride ceramics has become more and more extensive. The current applications of aluminum nitride ceramics are mainly in aerospace, electronic industry, semiconductor and other fields. Aluminum nitride ceramics have the characteristics of high strength, high hardness, high temperature resistance, corrosion resistance, wear resistance and high thermal conductivity of aluminum nitride ceramics. The hardness of aluminum nitride ceramics is second only to diamond.

Aluminum nitride, chemical formula ALN, is an important structural ceramic material. It is a superhard substance, resistant to wear and oxidation at high temperatures. Aluminum nitride ceramics can be prepared under normal pressure.

First of all: Aluminum nitride ceramics are second only to diamond, boron carbide and cubic boron nitride, and aluminum nitride ceramics ranks fourth in inorganic materials. At present, high-density aluminum nitride can be obtained by hot-pressing sintering method. It has high strength and good oxidation resistance, and can maintain no deformation under high temperature conditions. It can be used as turbine blades on high-temperature gas turbines. It can be used as a wear-resistant sealing material, and can also be used as a heating plate for heating silicon wafers in the semiconductor industry.

The hardness of aluminum nitride ceramics is very high, and it is difficult to process. If there is no advanced equipment or professional processing technology, it is estimated that it is difficult to process, and each of its processes is very important. If the craftsmanship is not in place, the material can be said to be directly scrapped.
