Product Description
Alumina ceramics has good insulation, thermal insulation and wear resistance, because the price is relatively cheap, and its comprehensive performance is balanced, is one of the widely used ceramic materials. High-purity (99.5% and above) alumina has good corrosion resistance and plasma etching resistance, and is widely used in pan-semiconductor devices.
Main features：
Insulation, thermal insulation, wear resistance, corrosion resistance, plasma etching resistance.
Main applications:
Pan-semiconductor equipment (LCD and LED and other manufacturing equipment) spare parts, insulation parts, wear parts, general machinery, hydraulic parts.
