Alumina Ceramic Block

Alumina Ceramic Block is an advanced engineering ceramic material with high-purity α-alumina (Al₂O₃) as the main component, made by high-temperature sintering process. Compared with other ceramic materials, this product has achieved excellent mechanical strength, hardness and wear resistance by virtue of its precise control of alumina content (usually 92%-99.9%). The Mohs hardness can reach 9, which is significantly higher than most metals and traditional ceramics. It has outstanding thermal stability and can maintain stable performance in a high temperature environment of 1650℃. It also has extremely low thermal conductivity and excellent electrical insulation (dielectric strength>10 kV/mm). In strong acid, strong alkali and corrosive gas environments, Alumina Ceramic Block exhibits chemical corrosion resistance far exceeding that of metal materials. These characteristics make it an irreplaceable key material in harsh industrial scenarios, especially suitable for fields with extremely high requirements for wear life, high temperature tolerance and insulation reliability.
