Zirconium Corundum ramming mass is composed of fused zirconium corundum granules by oxidation method and a small amount of additives. It has the characteristics of atmospheric temperature hardening, high strength at high temperatures, low thermal expansion and shrinkage, and strong resistance to glass liquid erosion. It is the ideal material for sealing the layer at the bottom of the glass furnace molten pool.
