Sintered zirconium-corundum bricks are sintered at high temperatures with zirconium and corundum minerals.
Liquid glass has the following characteristics, as strong erosive ability, high temperature resistance, good resistance to thermal shock, excellent creep resistance at high temperatures, high corrosion resistance to slag and glass liquid, etc., and is used in glass furnace grates, small ovens, working pools, domes and front cameras and other parts.
