Analysis of fire resistance performance of کروم کورنڈم اینٹوں

From the Al2O3-Cr2O3 binary phase diagram, we can see that Al2O3 and Cr2O3 can form a continuous solid solution without eutectic. Therefore, adding Cr2O3 to the high-purity corundum material, regardless of the amount added, will not only not reduce the fire resistance of the material, but will increase the fire resistance of the material. The refractoriness (>1790) and load softening temperature (>1700!) of chrome corundum bricks are better than high-purity corundum products.
