Dead Burned Magnesia (DBM), is produced through the high-temperature calcination of magnesite ore or caustic calcined magnesia at temperatures exceeding 1700°C in rotary or vertical kilns. This process results in a dense, crystalline structure primarily composed of magnesium oxide (MgO), offering superior thermal and chemical properties. This process removes volatile components and impurities, enhancing its refractory properties. Dead Burned Magnesia is crucial in manufacturing refractory bricks, monolithic refractories, and other high-temperature materials.
