Aluminium nitride’s performance index
(1) The thermal conductivity is high (about 320W/m*K), which is close to SiC. It’s more than 5x higher than Al2O3
(2) Matching the thermal expansion coefficients (4.5 x 10-6) and Si (3.54 x 10-6)
(3) various electrical properties (dielectric constant, dielectric loss, body resistivity, dielectric strength) excellent;
(4) The mechanical properties of BeO and Al2O3 ceramics are superior to their flexural strengths. They can also be atmospheric sintered.
(5) High optical transmission qualities;
Nano aluminum nitride used in thermallyconductive plastics
1. Thermally conductive silica gel or thermally conductive epoxy resin
Nano AlN composite silica Gel with high thermal conductivity is extremely efficient. This gel features excellent thermal conductivity and good electrical insulation. The operating temperature of the product ranges from -60 to 200 degrees Celsius. These products can replace or exceed imported products. They are widely used as heat transfer medium in electronic devices, which improves work efficiency. For example, CPU, radiator filling gap and silicon controlled components. Diodes. The purpose of nano thermal paste is to bridge the space between IC/audion and heat sink. It also increases the area between the two to improve heat dissipation.
2, application of thermally-conductive plastics:
Powders of nano-alluminium nitride can significantly improve plastic’s thermal conductivity. By adding the experiment product at a rate of 5-10% to the plastic, the plastic’s thermal conductivity can be raised from 0.3 to 5. More than 16 times more thermal conductivity. This product is superior to the existing thermal conductivity additive on the market. It has low addition amounts, improves mechanical properties and enhances thermal conductivity. Current nano aluminum nitride products have been purchased by large-scale application companies. New nano thermally conductive plastics will also be on the market.
3. There are other areas of application:
In smelting nonferrous metals, the semiconductor gallium arsenidecrucible, the evaporation vessel, thermocouple protection tub, heat insulation, micro dielectric materials and transparent aluminum Nitride microwave ceramic products and high temperature resisting and corrosion resistant structural ceramics, as well as in current application, PI resin and thermal insulating mica tap, thermal grease and heat conduction oils.
