Classification and characteristics of zirconia ceramics

- Oct 11, 2020-

Because of its sintering temperature is as high as 1650-1990 ℃, and the transmission wavelength is 1~6μm, it is generally made of molten glass to replace platinum crucible: use its light transmittance and alkali metal corrosion resistance as sodium lamp tube; It can be used as an integrated circuit substrate and high-frequency insulating material in industry. Ordinary alumina ceramics are divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain and other varieties according to different Al2O3 content. Sometimes those with Al2O3 content of 80% or 75% are also classified as ordinary alumina ceramic series. Alumina ceramics are widely used in various industries, including textiles, optoelectronics, semiconductors, automobiles, machinery, and solar energy. Smile has the most complete alumina production line, from raw material preparation to final processing, inspection, all produced by ourselves, and also has the most complete alumina material, covering various purity from 80%, 95%, 99%, 99.5%, 99.99% grade.
