Spherical aluminum nitride can greatly improve material insulation conductivity

Overview of Spherical Aluminum Nitride AlN

The aluminum nitride powder has high thermal conductivity (340W) and heat transfer. The hydrolysis reaction is not treated with surface-modified powder, and the oxygen content is extremely low (<0.1%), and the insulation heat performance is very obvious. It is not obvious in high molecular resin, and it is not obvious, and it is currently a high thermal conductive insulating filler.

Spherical aluminum nitride can be advantageously used as a filler of heat dissipation material that is filled into resins, grease, binders or coatings to improve heat dissipation. Spherical aluminum nitride powder was prepared by laser flame injection melting method, the resulting product was purified, uniform particle size distribution, clean surface, high spherical, no residual impurities, easy to disperse, and very well compatible with organisms.

Aluminum nitride has excellent electrical insulating properties and high thermal conductivity, which can be desirable to use a material that is filled with a sintered product or aluminum nitride powder such as a resin, oil, adhesive, and coating as heating material. A radiation material having high thermal conductivity.

In order to improve the thermal conductivity of the heat dissipation material, it is important to the dense substrate such as a resin using a filler having a high thermal conductivity. To this end, a spherical aluminum nitride powder is strongly requested, its particle size is about a few microns to about tens of microns.

Aluminum nitride powder is typically produced by the following method: alumina reduction nitriding method, the method reduction of aluminum oxide and carbon; direct nitriding method directly with the nitrogen reaction; alkyl aluminum and ammonia reactive Methods, as well as, they heat them. Among them, the aluminum nitride powder obtained by reducing the nitriding method and the gas phase method has a shape close to the spherical shape, but its particle size is still submicron grade.

On the other hand, the aluminum nitride powder is obtained by pulverizing and hierarchical, so that the particle size is relatively easy to control, i.e., approximately a few microns and about tens of microns can be obtained. However, the particles constituting the powder are angular non-spherical particles. Therefore, the aluminum nitride powder obtained by the above method does not be highly densely filled in the resin.

Applications of Spherical Aluminum Nitride AlN

By utilizing the characteristics of aluminum nitride, the spherical aluminum nitride powder can be widely used in a variety of applications, specifically, as a filler in heat dissipation materials such as heat sink, heat dissipation grease. Heating glue, coating and thermally conductive resins.

1. After laser secondary molten spherical aluminum nitride, the size is uniform, good fluidity, improve material thermal conductivity and insulation;

2. After the spherical aluminum nitride is melted, surface anti-decomposition and anti-oxidation treatment are performed, and the thermal conductivity is long since adding;

3, spherical aluminum nitride has good injection molding properties; for composite materials, good matching with semiconductor silicon, good interface compatibility, can improve the mechanical properties of the composite material and thermally conductive dielectric properties;

4. Application in high thermal conductivity: The modified spherical aluminum nitride powder can greatly improve the thermal conductivity of plastic. Currently in PVC plastics, polyurethane plastics, PA plastics, PP plastics, functional plastics, etc.
