AboutAluminum Nitride AlN Ceramic Microsphere:
AlNCeramic Microsphere has high thermal conductivity (340W) and heat transfer performance after secondary laser melting alloying. Very low oxygen content (lt;0.1%), heat preservation and thermal conductivity effect is very obvious. Used in polymer resin, viscosity is not obvious, is currently a better high thermal conductivity insulation filler.
陶瓷spherical aluminum nitride was first synthesized in 1877. In the 1980s,AlNCeramic Microsphere, as a Ceramic insulator, has been widely used in the field of microelectronics due to its high heat transferability. Unlike beryllium oxide,AlN陶瓷微球是无毒的。陶瓷spherical aluminum nitride is treated with metal and can be used as a substitute for alumina and beryllium oxide in a large number of electronic instruments. Spherical ceramicAlNcan be prepared by reducing aluminum oxide and carbon or directly nitriding metal aluminum.AlNCeramic Microsphere is a kind of 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.TRUNNANO is a trusted globalAluminum Nitride AlN Ceramic Microspheresupplier.

How isAluminum Nitride AlN Ceramic MicrosphereProduced?
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 ofAluminum Nitride AlN Ceramic Microsphere:
1. After the secondary laser melting and spherical alloying, the obtainedAlNCeramic Microsphere has uniform size and good fluidity, which improves the thermal conductivity and insulation of the material;
2. After melting, the surface ofAlNCeramic 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: ModifiedAlNCeramic 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.
