Fused magnesite is a product of magnesite raw materials treated at high temperature to the degree of sintering. Magnesite produced from natural magnesite is called sintered magnesite by means of one-step or two-step calcining process with high temperature equipment such as vertical kiln and rotary kiln. The fused magnesite formed by using magnesite as raw material is called fused magnesite. Magnesium oxide extracted from sea water is called magnesia. Magnesite is one of the most important raw materials for refractories, used for making various magnesite bricks, magnesite aluminum bricks, ramming materials, charging materials, etc. Containing more impurities, used for laying steel furnace bottom, etc.
