Aluminum nitride ceramic wafer

Aluminum nitride ceramic wafer is a kind of high-performance ceramic material, mainly made of aluminum nitride (AlN).

Excellent features:

1. High thermal conductivity: The thermal conductivity of aluminum nitride ceramic wafers is as high as 170 W/m · K, which is much higher than that of traditional ceramic materials such as alumina. Its thermal conductivity is 7-10 times that of alumina.
2. Excellent electrical insulation: with a breakdown strength of up to 17-19 kV/mm, ensuring safe operation in high voltage environments.
3. Low thermal expansion coefficient: The thermal expansion coefficient is 3.2-3 × 10/° C, which is similar to silicon materials and can effectively reduce the mechanical stress caused by temperature changes.
4. Excellent physical and chemical stability: the maximum operating temperature can reach 1000 ° C, high temperature resistance, chemical corrosion resistance, and stable performance under high temperature and humidity conditions.
5. Non-toxic and environmentally friendly: Aluminum nitride ceramics are non-toxic, do not produce dangerous vapors during grinding and processing, and meet the European Union ROHS environmental protection standards.
