Description
Description
A chrome corundum brick is a corundum refractory product containing Cr2O3. At high temperature, Cr2O3 forms a continuous solid solution with Al2O3, so the high temperature performance of chrome corundum products is better than that of pure corundum products. The application of more chrome corundum products, Cr2O3 content is mostly in the range of 9% to 15%. The main mineral composition is α-Al2O3-Cr2O3 solid solution.
