What is chrome corundum?
Chrome corundum brick is a refractory brick made of α-Al2O3 as raw material, adding appropriate amount of chromium oxide powder and chrome corundum clinker powder, after molding, and firing at high temperature.
The main mineral composition of chrome corundum brick is α-Al2O3-Cr2O3 solid solution. The secondary mineral composition is a small amount of composite spinel and refractory bricks with a chromium oxide content of 1% to 30%. There are two types of cast chrome corundum bricks and sintered chrome corundum bricks.
Chrome corundum bricks are widely used in zinc smelting electric furnaces and volatilization kilns. Chrome corundum bricks have excellent thermal shock stability and high temperature creep performance.
