The nano aluminum nitride is produced by aerosol ablation. It has high purity, small particles, high specific surface area, high surface activity, and a 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 resins. This is the current best filler to achieve high thermal conductivity insulation. The properties Nano Aluminium Nitroride

Nano-aluminum Nitride is a diamond like nitride that can be stabilised up to 2200 degrees. It has a high strength at room temperature and its strength increases slowly as the temperature rises. 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.

It is also good for injection molding.

A application of nano aluminium nitrogen

1. The materials can be used in the manufacture of electronic devices, optic devices, integrated circuits, high temperature crucibles, and high-temperature adhesives. 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 a good thermal conductivity. It has a good electrical insulation, a large operating temperature range (80-250°C), and a good consistency. 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 IC, triode, and heat sink. It also increases the contact surface between them to achieve a greater 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 oil is activated with high temperature and pressure. 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 a 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. The nano aluminum nitride modified powder can be used to improve thermal conductivity in plastics. Thermal conductivity in plastics can be improved by 10-30% using the experimental product. The main applications are PVC, polyurethane and PA plastics.

Other applications: Nano aluminum is used as a dielectric material, microwave dielectric, structural ceramics with high temperature and corrosion resistance, and in transparent aluminum nitride micro ceramic products.
