Aluminum nitride: What does that mean? Aluminum nitride AIN crystal exhibits a wurtzite structure. The chemical composition is AI 65.81% and N 34.19%. Its specific gravity is 3.261g/cm3, which can be white or grayish-white, with a single transparent crystal. Sublimation decomposition temperatures are 2450 degrees at atmospheric pressure. It can be used as a heat and temperature resistant material. Aluminum nitride can resist molten aluminum and other molten metals as well as gallium arsenide.
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 x10-6 ), Si (3.54 x10-6 ), and GaAs (6×10-6 ).
(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;
(6) non-toxic.
Nano aluminum nitride used in thermallyconductive plastics
1. Thermally conductive silica gel or thermal conductive epoxy resin
Nano AlN composite silica Gel with high thermal conductivity is extremely efficient. This gel features excellent thermal conductivity and high 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 thermal conductive materials:
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-alluminium nitride products have been purchased by large numbers of 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, evaporationboat and thermocouple protectiontube, heat insulation, micro dielectric materials and high temperature resistant, corrosion resistant structural ceramics. Transparent aluminum nitride microwave products are also used. The current application, PI resin and thermal insulating mica tap, thermal grease and heat conduction oils are all examples.
