Product Details

abrasion-resistant-ceramic


Alumina ceramic has a high degree of hardness and density, with a hardness of 9, slightly lower than diamond, and the volume density is generally greater than 3.5g/cm cubed, some of which can reach 4.0g/cm cubed. Alumina ceramics by Al2O3 content is divided into 99 porcelain, 95 porcelain, 90 porcelain, 85 porcelain, and other varieties, of which 99 alumina ceramics material used to make high temperature crucible, furnace pipe and special wear-resistant materials, such as ceramic bearings, seals, etc.; Alumina ceramics is mainly used as corrosion resistant and wear resistant parts.


Is widely used in coal-fired power plants, steel, smelting, machinery, coal, mining, chemical, cement, port terminals, and other enterprises of the coal transporting system, pulverizing system, ash discharge and dust removal system all wear large mechanical equipment, can according to the different requirements for different types of products.
