High temperature alumina powder for ceramic materials
Features: high temperature aluminum oxide powder is white powder, loose block, easy to crush, stable high temperature performance. High temperature aluminum oxide powder for ceramic materials is insoluble in water and difficult to dissolve in acid and alkali solution. It is calcined in tunnel kiln at high temperature, with long holding time and high calcination temperature. High temperature alumina is especially suitable for the production of ceramic products by grouting, and can also be used for film rolling, dry pressing, hot pressing and various electronic ceramics, with low shrinkage rate. The protocrystalline particles are 1 um-3 um.
Application: various electronic ceramics, high alumina refractories, unshaped refractories (high alumina castables), high temperature resistant ceramics, wear-resistant ceramics, electronic substrates, high alumina ceramics, roller bars, etc.
