Product Description
Alumina Ceramic
Aluminum oxide ceramics are divided into two types: high-purity type and ordinary type. The ordinary alumina ceramic system is divided into 99 ceramics, 95 ceramics, and other varieties according to the different Al2O3 content. Among them, 99 alumina ceramic materials are used to make high-temperature crucibles, refractory furnace tubes, and special wear-resistant materials,such as ceramic bearings, ceramic seals, and water valve plates; 95 alumina ceramics are mainly used as corrosion-resistant and wear-resistant components.
