It is a high-grade raw material for the manufacture of high-grade refractory products such as spinel and square magnesium with high strength and thermal shock stability. It can also be used to manufacture nozzle bricks and flat furnace bricks. It is also the basic raw material for large cement kilns refractory bricks and refractory casting materials. Widely used in steel smelting, cement rotary kiln and glass industry kiln.
