Calcined Magnesite 85% 200 Mesh Powder

Magnesite usually forms during the alteration of magnesium-rich rocks or carbonate rocks by metamorphism or chemical weathering. Magnesite is used to produce magnesium oxide (MgO), which serves as a refractory material for the steel industry and as a raw material for the chemical industry. Magnesium oxide (MgO) is one of the most important products of the refractory industry. It is usually produced by thermal decomposition of magnesite (MgCO3) or by a seawater process from magnesium hydroxide (Mg(OH)2). The type of raw material, the temperature of calcination and the impurities mostly affect the physical properties of MgO. Caustic calcined MgO is burned at temperatures below 900 °C. It is used in fertilizers, as animal feed and as a raw material for various MgO chemicals for the production of pulp and paper, ceramics and cements. A characteristic property of this MgO type is its moderate to high chemical reactivity. Because of this reactivity, it is imperative to search for…
