The salient features and practical applications of nano aluminium nitride

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 resins. This is the current best filler to achieve high thermal conductivity insulation. 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. The resistivity is 1015. It can also withstand high temperatures of up to 1400 degrees. It can significantly improve the thermal conduction of silicone rubber and polymers. It is a great thermal shock material.

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

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. Good application prospects. 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 characterized by good thermal conductivity. It has a good electrical insulation, a large operating temperature range (80-250 degrees), a lower consistency and a good construction performance. 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 will fill the gap that exists between the IC or triode and the heat sink. This will increase the area of contact between the two and provide a better heat-dissipating effect.

3. Nano-ceramic lubricating and anti-wear agent. Modified nano aluminum-nitride ceramics added to the nanoceramic engine oils act on metal surfaces inside the engine. They are activated when high temperatures and pressures 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. It can increase anti-wear by more 350% by improving lubrication. Reduce wear by up to 80%. Only 1/1000 to 2/10000.

4. Application to high thermal conductivity materials: The modified nano-aluminum nitride can significantly improve the thermal resistance of plastics. Thermal conductivity in plastics can be improved by 10-30% using the experimental product. This increases the conductivity from 0.3 up to 3 and more than 10x. The main applications are PVC, polyurethane and PA plastics.

Other applications: Nano aluminum-nitride ceramic products 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.
