Brown molten alumina is melt crystallized with high-quality bauxite at a high temperature above 2250 °C, carbon and iron As a raw material, the grinding wheel is made of abrasive brown molten alumina.
Our products It has the characteristics of high purity, good crystallinity, strong fluidity, low coefficient of linear expansion and good corrosion resistance. COuld does not burst, no crushing and CRApouch Use in the course Refractories.
