Application field
1. Manufacturing 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 very good application prospect, can replace the imported micron aluminum nitride;
2. Thermal conductivity silica gel and thermal conductivity epoxy resin: ultra-high thermal conductivity silica gel prepared by nano aluminum nitride has good thermal conductivity, good super electrical insulation, wide electrical insulation and service temperature (working temperature 80-250℃), lower consistency and good construction performance. Products have reached or exceeded imported products, because can replace similar imported products and widely used in electronic devices heat transfer medium, improve work efficiency. Such as CPU and radiator gap, high-power audion, thyristor element, diode, and the substrate contact with the thin seam of the heat transfer medium. Nanometer thermal conductivity paste is to fill the gap between IC or transistor and heat sink, increase the contact area between them, and achieve better heat dissipation effect;
3. Nanometer lubricating oil and antiwear agent, nanometer ceramic oil added in the modified aluminum nitride ceramic nanoparticles as lubricating 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. Because of 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 super anti-wear protection effect, by improving the lubrication, can decrease the friction coefficient of more than 80%, improve the antiwear ability by more than 350%, reduce wear and tear more than 80%, more than 3 times to extend the service life of machine parts, reduce downtime and reduce maintenance costs, prolong overhaul period more than double, Energy saving 10%-30%, increase the output power of the equipment 20%-40%, the addition amount is only 200%-1/1000;
4. Application of high thermal conductivity plastics: modified nano aluminum nitride powder can greatly improve the thermal conductivity of plastics. By adding 1% of the experimental products to the plastic, the thermal conductivity of the plastic can be increased from 0.3 to 3, and the thermal conductivity has been increased by more than 10 times. At present, it is mainly used in PVC plastic, polyurethane plastic, PA plastic, functional plastic, etc.
5. Other applications: nano aluminum nitride can be used in crucible melting non-ferrous metal and semiconductor material gallium arsenide, evaporation vessel, thermocouple protection tube, high temperature insulation, microwave dielectric material, high temperature and corrosion resistant structure ceramics and transparent aluminum nitride microwave ceramic products
