Light burned magnesium ball refractories refer to inorganic non-metallic materials with refractoriness over 1580 ℃. The refractoriness refers to the centigrade temperature at which the refractory cone specimen can resist high temperature without softening and melting down under no load. Refractory materials have a long history. Refractory materials combined with high temperature technology appeared in the middle of the Bronze Age; During the Eastern Han Dynasty in China, clay fire resistance appeared

Generally, light burned magnesium spheres refer to products containing more than 98% magnesium oxide, so that magnesium oxide has good alkali resistance and electrical insulation at high temperatures, good light permeability, high thermal conductivity, and large thermal expansion coefficient. Therefore, it is widely used in electronics, optics, instrumentation, metallurgy, national defense, aerospace and other fields. At present, China's demand for high-purity magnesium oxide is more than 100000 tons
