Aluminium nitride AIN ceramic component

 

Aluminium nitride AIN ceramic component with its excellent ability to dissipate heat up to 200 W/mK.

Chemical formula: When discussing materials with high thermal conductivity and electrical insulation properties, Aluminium Nitride (AIN) Ceramics often come to mind. An Aluminium Nitride(AIN)ceramics component is crucial in applications where these properties are essential.

The chemical composition is AI 65.81%, N 34.19%. Its powder is white or gray-white, and single crystals are colorless and transparent. Additionally, the sublimation decomposition temperature under normal pressure is 2450 °C.   

Characteristics of Aluminium nitride AIN ceramic:

High thermal conductivity (> 170W/m·K) is close to BeO and SiC. It is more than 5 times that of Al2O3. The coefficient of thermal expansion (4.5×10-6 °C) matches with Si (3.5~4×10-6 °C) and GaAs (6×10-6 °C). 

Excellent electrical properties include dielectric constant, dielectric loss, bulk resistivity, and dielectric strength. The mechanical properties are good, with flexural strength higher than Al2O3 and BeO ceramics. It can sintering under atmospheric pressure. 

Advantages of Aluminium Nitride AIN Ceramic:

High thermal conductivity, low expansion coefficient, high strength, and high temperature resistance make it ideal. Also, chemical corrosion resistance, high resistivity, and low dielectric loss are notable. Therefore, it is an ideal large-scale integrated circuit heat dissipation substrate and packaging material.
