Performance and Application of Aluminum Nitride AlN Ceramic Microspheres

Product performance of aluminum nitride AlN ceramic microspheres

 AlN has high thermal conductivity and electrical insulation. Adding AlN powder to resin or plastic can significantly improve thermal conductivity. The characteristics of aluminum nitride AlN ceramic microspheres: close to spherical, high solid load, good fluidity, good fluidity, sharp particle size distribution, high thermal conductivity, and high electrical insulation. 

Overview of aluminum nitride AlN ceramic microspheres

Ceramic spherical aluminum nitride was first synthesized in 1877. In the 1980s, AlN ceramic microspheres, as ceramic insulators, were widely used in the field of microelectronics due to their high heat transfer. Unlike beryllium oxide, AlN ceramic microspheres are non-toxic. Ceramic spherical aluminum nitride is treated with metal and can be used as a substitute for aluminum oxide and beryllium oxide in a large number of electronic instruments. Spherical ceramic AlN can be prepared by reducing aluminum oxide and carbon or directly nitriding metal aluminum. Aluminum nitride ceramic microspheres are a material connected by covalent bonds. It has a hexagonal crystal structure with the same shape as zinc sulfide and wurtzite. Industrial grade materials can only be made by hot pressing and welding. This material is very stable in an inert high temperature environment.

Application of Aluminum Nitride AlN Ceramic Microspheres

1. After the second laser melting and spherical alloying, the obtained AlN ceramic microspheres have uniform size and good fluidity, which improves the thermal conductivity and insulation of the material;

2. After melting, the AlN surface ceramic microspheres are treated with anti-hydrolysis and anti-oxidation, and the thermal conductivity will exist for a long time after being added.

3. Ceramic spherical aluminum nitride has good injection molding properties; used in composite materials, it has good matching and good interface compatibility with semiconductor silicon, which can improve the mechanical properties and thermal conductivity of composite materials;

4. Application in high thermal conductivity plastics: Modified AlN ceramic microspheres can greatly improve the thermal conductivity of plastics. At present, it is mainly used for PVC plastics, polyurethane plastics, PA plastics, PP plastics, functional plastics, etc.
