The nano aluminum nitride is produced by aerosol ablation. It has high purity, small particles, large specific surfaces and high surface activity. 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 high thermal conductivity insulation filler. 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, radiators, and high-temperature melting crucibles. They are also useful for the preparation of metal-based and composite materials. It can replace the micron aluminum alloy currently imported.

2. Thermally-conductive silica and epoxy resins: Ultra-high-thermally-conductive silica prepared with nano-aluminum nitride is a silica-based gel that has good thermal conductivity. It also provides good electrical insulation. These include the space between the CPU radiator and the 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-ceramic antiwear agent and nano lubricating engine oil: The nano aluminum nitride modified ceramic particles added to the lubricating engine oil are firm and infiltrate into the dents or micropores of the metal surface, repairing the damaged surface, and forming a nanoceramic protective layer. The film layer has an isolation effect that prevents friction from affecting the other parts. Nano-ceramics particles transform the friction between friction pairs into a rolling friction similar to small balls. The engine is protected from wear by reducing friction and friction between moving components to near zero. It can increase anti-wear by more 350% by improving lubrication. By doing so, it reduces friction coefficient by 80%. Only 2/10000 – 1/1000

4. The powdered nano-aluminum nitride can be used to improve thermal conductivity. 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.
