The basic classification of alumina ceramics
About the category of the alumina ceramic, there is still room for many need to discuss.
Alumina ceramics are divided into high purity type and ordinary type two kinds.
Type high purity alumina ceramic Al2O3 content in more than 99.9% of ceramic material, due to the sintering temperature up to 1650-1990 ℃, the transmission wavelength of 1 ~ 6 microns, usually made from molten glass to replace platinum crucible;Using alkali metal corrosion resistance is used as the transmission of light and sodium lamp tube;In the electronic industry can be used as a substrate integrated with high-frequency insulation.
Normal department of alumina ceramics by Al2O3 content is divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain, and other varieties, sometimes Al2O3 content in 80% or 75% are classified as ordinary alumina ceramic series.99 alumina ceramic materials used to make high temperature crucible, furnace pipe and special wear-resistant materials, such as ceramic bearings, seals and water valve, etc.;95 alumina ceramics is mainly used as corrosion resistant, wear resistant ceramic components;Because in 85 China often mixed with part of talc, improved the electric properties and the mechanical strength, with molybdenum, niobium, tantalum metal sealing, some used for electric vacuum devices.
We provide professional aluminum oxide wear resisting ceramics of various specifications of products, including: Wear ceramic liner,alumina ceramic mosaic,Alumina Ceramic Tile,wear resistant ceramic . at the same time provide a full improvement plan.
