The advantages and use of chrome corundum brick

 Chrome corundum bricks refer to corundum refractory products containing Cr2O3. At high temperatures, Cr2O3 and Al2O3 form a continuous solid solution, so the high temperature performance of chromium corundum products is better than pure corundum products. The chromium corundum bricks used in the gasification furnace of the petrochemical industry should be of low silicon, low iron, low alkali, high purity, and also have high density and strength. In the most widely used chromium corundum products, the content of Cr2O3 is mostly in the range of 9%~15%. The main mineral composition is α-Al2O3-Cr2O3 solid solution. The secondary mineral composition is a small amount of composite spinel (or no composite spinel), refractory bricks with a chromium oxide content of 1% to 30%. There are two types of cast chromium corundum bricks and sintered chromium corundum bricks. In general, chromium corundum brick refers to sintered chromium corundum brick.

In high purity corundum material add Cr2O3, no matter how much the amount, not only will not reduce the fire performance of materials，can make refractory performance of material improved.
