Calcined Alumina
Description:
Calcined Alumina is produced through the method of advanced high temperature down draught kiln with scientific calcination. High temperature calcined alumina powder is produced from industrial alumina as raw material.
Features:
Calcined Alumina has the properties of low water absorption rate, high true density, extremely low impurity content, excellent chemical activity.
Application:
Calcined alumina is widely used in refractory, ceramic filter, grinding, precise polishing, glass products,metal products, semi-conductivity materials, plastic, tapes, burnish belt. It is also used to produce slide gate sets, submerged nozzle, ladle shrouds, corundum bricks etc.
