SUOYI Aluminium nitride SUOYI China AlN high purity Nitride Aluminum powder CAS No.24304-00-5

1.Because of the piezoelectric properties of al nitride, the extensional extension of al nitride crystals is also used in surface acoustic wave detectors. The detectors are placed on silicon wafers. There are very few places where these thin films can be reliably made.

2.Aluminum nitride ceramics have high room temperature and high temperature strength, small coefficient of expansion, good thermal conductivity, can be used as high temperature structural parts of the heat exchange equipment materials.

3.Aluminum nitride ceramics can be used as crucible and casting mold material for melting of Al, Cu, Ag, Pb and other metals by virtue of its corrosion resistance of iron, aluminum and other metals and alloys.

Applications of Spherical Aluminum Nitride AlN Granule:

1. The manufacture of high-performance ceramic devices: manufacturing integrated electric subgrade board, electronic devices, optical devices, radiators, the high-temperature crucible

2. The preparation of metal and polymer matrix composite materials: especially in the high temperature sealing adhesive and electronic packaging materials have excellent application prospects.

3.Nano inorganic ceramic automotive lubricants and anti-wear agent, nanometer ceramic aluminum nitride ceramic nanoparticles as lubricating oil in the metal surface on the engine internal friction pair, 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 a nano-ceramic coating. Because of the isolation of this film, friction is greatly reduced, reducing the friction between moving parts to almost zero. Although the price of nano aluminum nitride powder is expensive, the amount added in the lubricating oil is only two parts per ten thousand, the cost performance is very high.

4. Used for manufacturing heat-conducting silica gel and heat-conducting epoxy resin. Ultra-high thermal conductivity nano-aluminum nitride composite silica gel has good thermal conductivity, good electrical insulation, wide electrical insulation temperature (working temperature -60℃ –200℃), low consistency and good construction performance. Widely used in the gap between CPU and radiator, high-power triodes, SCR components, diodes, and the heat transfer medium in the thin joints in contact with the substrate.

5. Aluminum nitride powder in the application of high thermal conductivity silicone rubber: At the end of the aluminum and silicon nitride matching performance is good, easy to disperse in rubber, on the premise of not affect the mechanical properties of the rubber can greatly enhance the thermal conductivity of silicone rubber, unlike oxides in the process of adding the viscosity rise quickly, add a small amount of (according to the requirements of thermal conductivity is in commonly 5% can make heat conductivity increased by 50% – 70%), widely used and the military, Aviation and information engineering.

6. Other areas of application: application of nano aluminum nitride in smelting non-ferrous metal and semiconductor gallium arsenide crucible, evaporation boat, thermocouple protection tube, high-temperature insulation parts, microwave dielectric ceramic materials, high temperature resistant and corrosion resistant structure and microwave transparent aluminum nitride ceramic products, and the current application and PI resin, thermal insulating mica tape, thermal grease, insulating paint, and heat conduction oil, etc.
