APPLICATION

through high temperature burning, chrome oxide green of acid showed inertia of acid and alkali, is great refractory material. Usually added to corundum or corundum spinel refractory materials, can significantly improve the performance of high temperature strength, slag resistance, ect. It mainly used in non-ferrous smelting industry, petrochemical industry, glass industry and also in castable, ramming material, and other unshaped refractory materials.
