Aluminum oxide ceramics are a type of ceramic material mainly made from AL203. Aluminum oxide ceramics are widely used and have a large output, and are commonly used ceramic materials. They are mainly divided into 99 aluminum oxide, 96 aluminum oxide, and 95 aluminum oxide ceramics. Application scope: Mainly used in mechanical, electronic, power, chemical, medical, aviation and other fields. The main advantages are high mechanical strength, good electrical insulation, high hardness and melting point, good corrosion resistance, excellent chemical stability, etc. Under certain conditions, it has good optical and ionic conductivity. Aluminum oxide ceramic substrate, high temperature resistance, high electrical insulation performance, low dielectric constant and loss, high thermal conductivity, good chemical deposition stability, is a widely used ceramic product
