Spherical AlN powder is a new high-tech ceramic

Spherical AlN powder is prepared by laser flame jet fusion method. The obtained product has high purity, uniform particle size distribution, clean surface, high sphericity, no residual impurities, easy dispersion, and good compatibility with organisms. Spherical AlN powder undergoes the second laser melting spherical alloying, and has a high thermal conductivity (340W) and heat transfer. The powder treated by surface modification will not undergo hydrolysis reaction. The oxygen content is extremely low (<0.1%), and the insulation and thermal conductivity effect is very obvious. Used in polymer resins, the viscosity is not obvious, and it is currently a good high thermal conductivity insulating filler.

Spherical AlN powder was first synthesized in 1877. In the 1980s, Spherical AlN powder was a ceramic insulator and Spherical AlN powder had a high heat transfer capacity, so that Spherical AlN powder was widely used in microelectronics. Unlike beryllium oxide, Spherical AlN powder is non-toxic. Spherical AlN powder is treated with metal, which can replace alumina and beryllium oxide in a large number of electronic instruments. Spherical AlN powder can be prepared by the reduction of aluminum oxide and carbon or directly nitriding metal aluminum. Spherical AlN powder is a substance connected by covalent bonds. It has a hexagonal crystal structure, which is the same shape as zinc sulfide and wurtzite. Industrial-grade materials can only be manufactured by hot pressing and welding. The substance is very stable in an inert high temperature environment.

Advantages application

1. After the second laser melting, spherical alloying, The Spherical AlN powder has uniform size, good fluidity, improve the thermal conductivity and insulation of the material;

2. After the Spherical AlN powder is melted, the surface is treated with anti-hydrolysis and anti-oxidation, and the thermal conductivity will exist for a long time after adding;

3. Spherical AlN powder has good injection molding properties; used in composite materials, it has good matching 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: The modified Spherical AlN powder can greatly improve the thermal conductivity of the plastic. Currently mainly used in PVC plastics, polyurethane plastics, PA plastics, PP plastics, functional plastics, etc.
