Dead Burned Magnesia

During sintering (firing) at temperatures of 1750 – 2000 C° in shaft or rotary kilns naturally occurring magnesium carbonate is converted into sintered magnesia, directly (one-step calcination process) or via caustic calcined magnesia (two-step). Dead Burned Magnesia can also be produced in a flotation where rejects or lower category raw stone is milled and impurities are washed out. Material is briquetted, caustic calcined, then fused, screened and crushed. Based on the lack of reactivity (e.g. with water, acids etc.) the commonly used term is Dead Burned Magnesia. Due to its heat resistant and insulating properties Dead Burned Magnesia (like electrofused magnesia) is ideally suited to the production of the highest quality refractory products. Dead Burned Magnesia is a basic component for the production of formed and unformed refractory products, bricks, prefabricated shapes, masses and mortars. It is mainly used in the steel industry and in cement production. In addition to production processes based on natural magnesium carbonate, there are also manufacturing methods based on chemical precipitation from seawater or brine.
