How about the thermal shock stability of high-performance chromium corundum bricks?

According to data, when Cr2O3 is added to corundum, when the content of Cr2O3 is 10%~66%, the thermal shock stability of the material decreases with the increase of Cr2O3 content, that is, chromium corundum bricks with low Cr2O3 content have good thermal shock stability. Used in chrome corundum bricks with high Cr2O3 content.
