Corundum products and corundum-mullite products have properties of good thermal shock resistance, high strength at high-temperatures and high density. They are widely used in glass furnace, cement kiln, heaters molten steel ladle, metallurgical furnaces for non-ferrous metals and furnace for chemical engineering industries.High purity low silicon corundum brick SiO2<0.5%, Al2O3>98%, used in petrochemical industry furnace, gasification furnace and large fertilizer equipment, and more than 1600° C super high temperature furnace, liner of furnace. Long life and reliable in quality. We can makde different kinds of shape products according the customer's drawing.
