High purity magnesia

High-purity magnesia is made of natural super-grade magnesite ore by flotation purification, light sintering, fine grinding, high pressure ball pressing, and ultra-high temperature shaft kiln calcination. It is a high-quality raw material for making bricks and unshaped refractories. The magnesium content is mgo96-97%. It is used as ideal raw material for high-grade magnesia refractory materials such as magnesia bricks, magnesia bricks, magnesia carbon bricks, ramming materials for tundish, and magnesia castables.
