Product Introduction
| Sintered Corundum Brick | |
| Corundum bricks are refractory bricks with an alumina content greater than 85%. Corundum bricks are divided into sintered and fused corundum bricks. Zircon corundum refractory bricks are high-grade refractory bricks made by adding ZrO2 to corundum, forming at high temperature, and sintering at high temperature The two types of refractory bricks have differences : Firstly, there are differences in high-temperature resistance.The fire resistance of zirconia corundum bricks is greater than 1790 ℃ and the load softening temperature is greater than 1700 ℃. The service temperature of zirconia corundum refractory bricks is 1600 ℃, and the high-temperature performance of zirconia corundum refractory bricks is better than that of pure corundum bricks. Furthermore, There is different in C.C.S.The compressive strength of corundum refractory bricks is 70-100MPa, while the C.C.S.of zirconium corundum bricks is greater than 100MPa. | |
