Products Description:
Sicheng tabular alumina is made of Al2O3, after ingredients, grinding and forming, smelting in high temperature furnace turned to α- Al2O3.
Tabular alumina has good heat resistance and good bulk temperature thermal shock capabilities. The crystal staggered plate shape, to increasing the mechanical strength of the particles
