Strength analysis of high-performance chromium corundum bricks

The room temperature compressive strength of high-purity corundum bricks is generally 70-100MPa, and the room temperature compressive strength of high-performance chromium corundum bricks is generally >150MPa, and its strength is significantly higher than that of corundum bricks. This is due to the formation of Al2O3-Cr2O3 solid solution between the particles and the particles, between the particles and the fine powder, and between the fine powder and the fine powder during the firing process of the product. The solid solution connects the particles and the fine powder like a bridge. Together, the strength of the material is greatly improved.
