Dead Burned Magnesite is made of natural material magnesia and calcined in high-temperature shaft kiln. Dead burnt magnesia is the raw material for making bricks and producing unshaped refractories, and the finished magnesium oxide are used for steel making, electric furnace bottom, and ramming furnace lining.
