High-Performance Calcined Alumina Powder：
a- Al203 has good high temperature performance, Calcined Alumina Powder is widely used in ceramic industry, monolithic refractories and shaped refractories products. According to the degree of grinding and crystal size, Calcined Alumina Powder plays the different roles in ceramics and refractory industry.
1. Increase the content of alumina in the using of natural raw material formula in order to improve the refractoriness and mechanical properties.
2. Increase the amount of fine powder accumulate in order to improve the mechanical strength and wear resistance.
3. Through the reaction with binder such as cement into the stability of high refractoriness, and excellent reting matrix.
