2. Small particle size distribution,
3. Surface area,
4. Low high surface activity, bulk density,
5. Good performance injection molding;
6. Used for composite materials, semiconductorsilicon matching, interface compatibility, and can be improve the mechanicalproperties and thermal properties of the composite dielectric.
Application for Nano Aluminum Nitride Powder:
1. The thermal conductivity of the nano composite of silica gel or resin:
AlN nano-silica composite has excellent thermalconductivity and electrical insulation, a wide temperature electricalinsulation, low consistency and good formability. Products for use in the heattransfer medium of electronic devices, improve work efficiency. Such as the CPUand heat sink caulking, power transistors, thyristors, diodes, heat transfermedium at the slit in contact with the substrate.
2. Nano inorganic ceramic automotive lubricants and anti-wear agents
Nano-ceramic oil nano aluminum nitride ceramic particles with the oil spread along the friction inside the engine metal surface, on the one hand, under high pressure is firmly embedded into the metal surface infiltration dents and micropores, repair damaged surfaces to form nano-ceramic reinforced metal surfaces. This layer of the diaphragm membrane,nano-ceramic particles like little balls as part of the friction between the friction from the traditional sliding friction into rolling friction, therebygreatly reducing friction and wear on the engine play super protection.
3. High thermal conductivity in plasticsapplications
Nano-aluminum nitride powder improves thethermal conductivity of plastics. Experiments with 1% of the product added tothe ratio of the plastic, the plastic can improve the thermal conductivity fromthe original 0.3 to 5. Thermal conductivity increased by 16 times.
4. Other application areas: nano-aluminum nitride used in non-ferrous metal smelting and gallium arsenide semiconductormaterial crucible evaporation boat protection tube, thermocouple, hightemperature insulation, microwave dielectric materials, high temperature andcorrosion resistant structural ceramics and microwave transparent aluminumnitride ceramics.
