Corundum Fire Brick Introduction

Corundum brick is a refractory product with the content of alumina more than 90%, which have the characteristics of  high cold compressive strength (up to 340MPa), high load softening start temperature (more than 1700 degrees C), strong resistance to acid or basic slag, metal and glass liquid. Corundum  fire bricks are fired at high temperatures to form a matrix with mullite, mullite-corundum or corundum that has excellent volume stability.
