High-purity alumina ceramics

- Mar 13, 2019-

High-purity alumina ceramics are ceramic materials with an Al2O3 content of more than 99.9%. Because their sintering temperature is as high as 1650-1990 ° C and transmission wavelength is 1 to 6 μm, they are generally made of molten glass to replace platinum crucibles. Properties and resistance to alkali metal corrosion used as sodium lamps; in the electronics industry can be used as integrated circuit substrates and high-frequency insulation materials.
