Magnesium magnesite can be calcined and melted at different temperatures to produce light burnt magnesia, heavy burnt magnesia powder and fused magnesia with the main component of magnesia.
Magnesite calcined at 750-1100 temperature is called "light burning". Its product is called light burning magnesia powder, referred to as light burning powder. Light-burning powder mainly produces cementitious materials, building materials for insulation and sound insulation, and also can be used as raw materials for ceramics.
Re-burned powder is mainly made from light-burned powder by water separation, hydrolysis, solid-liquid separation, drying, calcination and grinding. The production of heavy magnesia requires high quality of light-burned magnesia powder. In general, high-grade magnesite powder should be selected, and there should be no damp agglomeration.
