1. Nano aluminum nitride can be used as high thermal conductivity filler for heat conduction paste, heat conduction silicone grease, epoxy resin heat conduction pouring and sealing adhesive, etc. The ultra-high thermal conductivity silica gel prepared with it has good thermal conductivity, good electrical insulation, wide electrical insulation and service temperature, low consistency and good construction performance. It is widely used as a heat transfer medium for electronic devices. Such as CPU and radiator gap, high power triode, silicon controlled components, diodes, and substrate in contact with the slit of the heat transfer media. Nano thermal conductivity paste is to fill the gap between IC or triode and heat sink, increase the contact area between them, to achieve better heat dissipation effect.
2. The nanometer aluminum nitride can be used as lubricating oil and antiwear agent, nanometer ceramic aluminum nitride ceramic nanoparticles as lubricating oil in the oil on the engine internal friction pair of metal surface, under the action of high temperature and extreme pressure is activated, and strong permeability embedded in the metal surface dent and microporous, repair the damaged surface and form nano ceramic coating, strong protection of engine.
3. Aluminum nitride powder has high purity, small particle size and high activity, and is the main raw material for manufacturing high thermal conductivity aluminum nitride ceramic substrates. Aluminum nitride ceramic substrate is an ideal large scale integrated circuit heat dissipation substrate and packaging materials.
4. Aluminum nitride can be used as crucible for melting of aluminum, copper, silver, lead and other metals and as materials for sintering and casting molds.
5. The AIN ceramics can be used to make GaAs crystal crucible, Al evaporating dish, magnetohydrodynamic power generation device and corrosion resistant components of high temperature turbine, and its optical properties can be used as the infrared window.
6. The high-purity aluminum nitride film can be made into high-frequency piezoelectric components, ultra-large scale integrated circuit substrates, electronic devices, optical devices, heat sinks, high-temperature crucible to prepare metal and polymer matrix composites.
