Specification :

1. Calcined Alumina
Produced under 1350-1450, calcined in a rotary kiln of Æ2.5x56m, it has the characteristics of stable crystalline phase, good flowability, hardly soluble in acid and alkali, and excellent sintering property. Used as high quality material for aluminous refractory, sintering coroundum and electric ceramics.
2. Fine Calcined Alumina Powder
A white powder, uniform in grain size, low in moisture, stable in chemical performance. Used as raw materials for aluminous refractory, ceramic products, sparking plugs and grinding materials. It is the basic material for aluminous refractory and high quality fillers with strong fire-retardant performance.
