Alumina Ceramics are ceramic materials based on alumina (Al2O3) for thick film integrated circuits. Alumina ceramics have good conductivity, mechanical strength and high temperature resistance. It should be noted that ultrasonic cleaning is required. Alumina ceramics is a versatile ceramic. Because of its superior performance, it has been widely used in modern society, satisfying the needs of daily use and special performance.The high-purity alumina ceramics have a Al2O3 content of 99.9% or more. Since the sintering temperature is as high as 1650-1990 ° C and the transmission wavelength is 1 to 6 μm, the molten glass is generally used to replace the platinum crucible; Sexual and alkali-resistant metal corrosion is used as a sodium lamp; it can be used as an integrated circuit substrate and high-frequency insulation material in the electronics industry.
