Light Burned Magnesium Oxide Powder, also known as light burned magnesia or caustic magnesia, is a white or off-white powder produced by calcining magnesium hydroxide extracted from dolomite, brucite, seawater, or brine at a temperature of approximately 800-1000 ℃. The powder is loose in texture and highly chemically reactive. It can be used in producing magnesium cement, magnesite building materials, thermal insulation materials, and more. Additionally, it serves as an intermediate product for producing high-quality magnesia through the two-step calcination process.
