Dead burnt magnesia means that when magnesite is calcined at 1800 ℃, carbon dioxide completely escapes, and magnesium oxide forms a dense block of periclase, called dead burnt magnesia (also known as sintered magnesia). of refractoriness. Its main component is magnesium oxide, which is made of natural super-grade magnesite ore through flotation purification, light burning, fine grinding, high pressure briquetting, and ultra-high temperature oil shaft kiln calcination.
