The following is a list of the most recent articles about Aluminum Nitride AlN Ceramic Microsphere : Aluminum Nitride This non-oxide material is primarily composed of aluminum and Nitrogen (AL 65.81% N 34.19). Aluminum Nitride Chemical Formula AlN.
AlN Ceramic Microsphere The alloys with secondary laser melting have a high thermal transfer efficiency (340W) as well as high thermal conductivity. It has a very low oxygen level (lt;0.1%) and the effect on heat retention and thermal conductivity is quite obvious. Viscosity in polymer resins is not noticeable, and it is currently the best insulation filler for high thermal conductivity.
Ceramic spherical Aluminum Nitride The first time it was synthesized was in 1877. In the 1980s. AlN Ceramic A Ceramic insulator called Microsphere has been used extensively in the microelectronics field due to its excellent heat transferability. AlN Ceramic Microsphere has a non-toxic nature, unlike beryllium. The ceramic spherical aluminium nitride can be treated with metal to be used in electronic instruments as a replacement for alumina or beryllium. Spherical ceramic AlN AlN Ceramic Microspheres is a material with covalent bonds. It has a hexagonal crystalline structure, similar to zinc sulfide. Only hot pressing and welding can produce industrial-grade material. This material remains stable even in a high-temperature inert environment.

How is Aluminum Nitride AlN Ceramic Microsphere Produced?
Spherical aluminum nitride ceramics were prepared by laser flame melting. The product has the advantages of high purity, uniform particle size distribution, clean surface, high sphericity, no residual impurities, easy dispersion and good compatibility with organisms.

Applications of Aluminum Nitride AlN Ceramic Microsphere:
1. After the secondary laser melting and spherical alloying, the obtained AlN Ceramic Microsphere has uniform size and good fluidity, which improves the thermal conductivity and insulation of the material;
2. After melting, the surface of AlN Ceramic Microsphere is treated with resistance to hydrolysis and oxidation, and the thermal conductivity exists for a long time after addition.
3. Ceramic spherical aluminum nitride has good injection molding performance; Used in composite materials, it has a good match with semiconductor silicon and good interface compatibility, which can improve the mechanical properties and thermal conductivity of composite materials;
4. Application in high thermal conductivity plastics: Modified AlN Ceramic Microsphere can greatly improve the thermal conductivity of plastics. At present, it is mainly used in PVC plastics, polyurethane plastics, PA plastics, PP plastics, functional plastics, etc.

Storage Condition of Aluminum Nitride AlN Ceramic Microsphere:
The damp reunion will affect aluminum nitride (AlN) ceramic microsphere dispersion performance and using effects, therefore, aluminum nitride (AlN) ceramic microsphere should be sealed in vacuum packing and stored in a cool and dry room, the aluminum nitride (AlN) ceramic microsphere can not be exposure to air. In addition, the aluminum nitride (AlN) ceramic microsphere should be avoided under stress.
