Technical Description of aln powder

Nano aluminum nitride powder and ultrafine aluminum nitride powder were prepared by variable current laser ion beam gas phase method, with high purity, small particle size, large specific surface area and high surface activity. After surface modification, no hydrolysis reaction occurred, oxygen content was very low (<0.1%), and the effect of insulation and thermal conductivity was very obvious.  Used in polymer resin, viscosity is not obvious, is a good high thermal conductivity filler.

Nano aluminum nitride belongs to diamond-like nitride, which can be stable to 2200℃ and has high strength at room temperature, and the strength decreases slowly with the increase of temperature.  Of ultrafine aluminium nitride has good thermal conductivity, thermal expansion coefficient, thermal conductivity, the theoretical value of 320 w/mk and copper, almost at the same time, high insulation, resistivity above 10 of 15 to the power, and high temperature resistant to 1400 degrees, can raise the thermal conductivity of plastic and silicone rubber, is a good material of heat shock, resistance to molten metal erosion ability is strong,  It is an ideal crucible material for melting and casting pure iron, aluminum or aluminum alloy.  High purity aluminum nitride powder has excellent electrical insulation and dielectric properties.

Nano aluminum nitride has good properties of injection molding.  Used for composite materials, good matching with semiconductor silicon, good interface compatibility, can improve the mechanical properties and thermal and dielectric properties of composite materials.

Application of aln powder

1.Nano aluminum nitride, ultrafine aluminum nitride is applied to manufacture integrated substrate, electronics, optics, radiator, high temperature crucible preparation of metal matrix and polymer matrix composites, especially in high temperature sealing adhesive and improve the cooling performance of the material in the electronic packaging materials and strength characteristics, have a good application prospect, can replace the import of high purity aluminium nitride;

2.Nano aluminum nitride, ultrafine aluminum nitride applied to thermal conductive silicone and thermal conductivity of epoxy resin of high thermal conductivity filler: use my company's production of high purity aluminum nitride with high thermal conductivity silica gel is prepared, it has good thermal conductivity, good electrical insulation, electrical insulation and use temperature of the wide (working temperature 80-250 ℃), low consistency and good construction performance.  Products have reached or exceeded imported products, because can replace similar imported products and applied in electronic devices heat transfer medium, improve work efficiency, is a good high thermal conductivity filler.  Such as CPU and radiator gap, high power triode, thyristor components, diodes, and the substrate in contact with the thin seam heat transfer medium.  Nano thermal paste is to fill the gap between IC or audion and heat sink, increase the contact area between them, to achieve better heat dissipation effect;

3.Nnano aluminum nitride powder, ultra-fine aluminum nitride powder applied to nano lubricating oil and antiwear agent:  The modified nano aluminum nitride ceramic particles added in the nano ceramic oil act on the metal surface of the friction pair in the engine with the lubricating oil, and are activated under the action of high temperature and extreme pressure, and firmly infiltrate into the dents and microholes on the metal surface, repair the damaged surface, and form the nano ceramic protective film of superfine aluminum nitride powder.  Because the membrane separation effect, make the effects of the friction is relative motion between the parts in this layer of protective film, nano ceramic particles like small ball will be part of the friction between the friction pair by traditional sliding friction into rolling friction, thereby greatly reducing the friction, the friction between moving parts dropped to near zero, the engine has strong anti-wear protection,  By improving lubrication, it can reduce friction coefficient by more than 80%, improve anti-wear ability by more than 350%, reduce wear by more than 80%, prolong the life of mechanical parts by more than 3 times, reduce downtime, reduce maintenance costs, prolong overhaul period by more than twice, save energy by 10%-30%, improve equipment output power by 20%-40%,  The amount added is only two to one part per thousand;

4.The application of high thermal conductivity plastic: modified nano ultra fine aluminum nitride powder can greatly improve the thermal conductivity of plastic.  By adding the experimental product to the plastic at 1-3%, the thermal conductivity of the plastic can be increased from 0.3 to 3, increasing the thermal conductivity by more than 10 times.  At present, it is mainly used in PVC plastic, polyurethane plastic, PA plastic, functional plastic, etc.

5.Nano aluminum nitride powder in other application fields: ultra-fine aluminum nitride powder can be used in the smelting of non-ferrous metals and semiconductor materials gallium arsenide crucible, evaporation boat, thermocouple protection tube, high temperature insulation, microwave dielectric materials, high temperature and corrosion resistance structure ceramics and transparent high purity aluminum nitride microwave ceramic products.
