    The product has high purity, small particle size, uniform distribution, large surface area, high surface activity, low bulk density and good injection molding performance. It is suitable for composite materials and has good compatibility with semiconductor silicon. Improve the mechanical properties of composite materials and thermal conductivity of dielectric properties.

    The main purpose:

    Manufacture high-performance ceramic devices:

    (1) Manufacture integrated circuit substrate: aluminum nitride ceramic material has excellent thermal conductivity, reliable electrical insulation, low dielectric constant and dielectric loss, can be used to manufacture high thermal conductivity ceramic substrate.

    (2) Electronic devices: in the production of ultra-large scale integrated circuits, electronic devices on the higher heat requirements, A12O3 has been unable to meet the cooling requirements, and the use of nano-ALN devices can be a very good solution to this problem.

    (3) Radiator: ALN thermal conductivity is about 10 times the A12O3, so the aluminum nitride prepared by the radiator can better heat to meet the different cooling requirements.

    (4) High temperature crucible: ALN can be stable at 2200 high temperature, and the strength decreases with increasing temperature slow, anti-molten metal erosion ability, is casting pure iron, aluminum or aluminum alloy ideal crucible material.

    Preparation of polymer-based composite materials: ALN has excellent electrical insulation, good dielectric properties, good compatibility with polymer materials, electronic products is an excellent polymer additive.

    Nano-inorganic ceramic vehicle lubricants and anti-wear agent: nano-aluminum nitride ceramic particles with the role of lubricating oil can be embedded into the metal surface dent and pores, the formation of nano-ceramic protective film. Because of this layer of membrane isolation, by improving the lubrication, can reduce the friction coefficient of more than 70%, improve anti-wear ability of more than 300%, can extend the life of mechanical parts more than 3 times, reduce maintenance costs, energy saving 5% -30% Output power of 15% -40%, and its added amount is only two ten thousandths.

    Thermal silica and thermal conductivity Epoxy: ultra-high thermal conductivity Nano-ALN composite silicone has good thermal conductivity, electrical insulation, low consistency and good construction performance. Widely used in electronic devices heat transfer medium, thereby improving work efficiency. Such as CPU and radiator caulking, high-power transistor and thyristor components in contact with the substrate at the joints of the heat transfer medium.

    The application of thermal plastic: nano-aluminum nitride powder can greatly improve the thermal conductivity of plastic. Through the experimental product to 5-10% of the proportion of added to the plastic, can make the thermal conductivity of plastic from the original 0.3 to 5. Compared with the current market, alumina or magnesium oxide and other thermal filler with a low amount of added to the mechanical properties of products to improve the role of thermal conductivity to improve the more obvious features.

    High thermal conductivity of silicone rubber applications: good match with the silicon, easy to disperse in the rubber, rubber can not affect the mechanical properties of the premise of a substantial increase in the thermal conductivity of silicone rubber, and the amount of small addition (according to thermal requirements generally About 5% can make the thermal conductivity increased by 50% -70%), is widely used in military, aviation and information engineering.

    Other applications: nano-aluminum nitride used in smelting non-ferrous metals and semiconductor materials gallium arsenide crucible, evaporation boat, thermocouple protection tube, high temperature insulation, microwave dielectric materials, high temperature and corrosion-resistant structural ceramics and transparent nitrogen Aluminum foil ceramic products, and currently used in PI resin, thermal insulation mica tape, thermal grease, insulating paint and heat transfer oil.


    This product should be stored in a cool, dry room, and avoid stress. The powder without the treatment of surface should not be exposed to the air during the use, to aviod absorb moisture agglomeration, affect the dispersion performance and the use of results.
