Aluminum Niride(AlN) Ceramic Substrate Ceramic Heatings

Characteristic:
（1）High thermal conductivity, which is more than 5 times that of alumina ceramics.
（2）Low thermal expansion coefficient, which is close to silicon chip.
（3）Lower permittivity.
（4）Excellent insulation performance.
（5）Excellent mechanical properties. The flexural strength is higher than Al2O3 and BeO ceramics, and could be atmospheric sintering;
（6）Heat resistance, corrosion resistance of molten metal.
