The nano aluminum nitride is produced by aerosol ablation. It has high purity, a very small particle, high specific surface area, high surface activity, and large specific surface. The powder that has been surface modified will not undergo hydrolysis and have a very low oxygen content. Insulation and thermal conductivity are very evident (0.01%). The viscosity does not show up when used in polymer fillers. This is the current best insulating material with high thermal conductivity. The properties Nano Aluminium Nitroride

The resistance is 1015, it can withstand a high temperature of 1400 degrees, and has a small thermal expansion coefficient. Its resistivity is 1015. And it can handle temperatures as high as 1400 degrees. It can significantly improve the thermal conduction of silicone rubber and polymers. It is a thermal shock resistant material.

Nano aluminum nitride exhibits good properties for injection molding; it also has excellent electrical insulation.

A application of nano aluminium nitrogen

1. The materials can be used in the manufacture of electronic devices, optic devices, integrated circuits, crucibles at high temperatures, and high-temperature adhesives. It can replace the micron aluminum alloy currently imported.

2. Thermally-conductive silica and thermally-conductive epoxy resins: Ultra-high-thermal-conductive silica prepared with nano-aluminum nitride is characterized by good thermal conductivity. It has a good electrical insulation, a large operating temperature range (80-250 degrees), and a low consistency. These include the space between the CPU radiator, high power transistors, thyristors components, diodes and the heat transfer material at the slits that are in contact with substrate. Nano thermal paste fills the gap between ICs and triodes, increases the contact surface between them and improves heat dissipation.

3. Nano lubricating and anti-wear agent. Modified nano aluminum-nitride ceramics added to the nanoceramic engine oils act on metal surfaces inside the engine. This lubricating and anti-wear agent is activated when high temperatures and pressure are applied. The film layer has an isolation effect that prevents friction from affecting the other parts. The nano-ceramic particle changes the friction between friction pairs to rolling friction. The engine is protected from wear by reducing friction and friction between moving components to near zero. By improving the lubrication it can reduce friction coefficient by over 80%. Increase the anti-wear abilities by more 350%. Only 2/10000 – 1/1000

4. Application in high-thermal conductivity plastics. The modified nano aluminum powder can significantly improve the conductivity of plastics. Thermal conductivity in plastics can be improved by 10-30% using the experimental product. The main applications are PVC, polyurethane and PA plastics.

5.Other applications: Nano aluminum-nitride ceramics can be used as crucibles to melt non-ferrous metals or semiconductor materials such as gallium arsenide. It is also suitable for thermocouple protection tubes and other high temperature insulating components.
