Fused magnesia It is an alkaline refractory with high purity, high melting point and compact structure, which is widely used in many fields such as metallurgy industry, glass industry, cement industry, household appliances heater and high-temperature chemical industry. It is not only because the melting point of MgO is 1800 ℃, which is higher in oxides, but also because its resistance to chemical attack of alkaline slag and alkaline oxides is extremely high.

The fused magnesia is made from magnesite or light burned magnesium (MgO) by melting in a three-phase electric arc furnace. The appearance of large crystal fused magnesia is transparent crystal. It is a high-tech product in the field of fused magnesium. It is used in many fields, such as high magnesium software and far-infrared receivers in metallurgical aerospace industry, nuclear industry, optical and electronic industry, substrate materials of superconducting materials, high-temperature peep glasses, etc.
