Dead-burned magnesia system products, including highly pure magnesia, medium magnesia and conventional magnesia, which contains MgO from *0% to *8%. Meanwhile we product electric-fused magnesia, electric-fused iron-chrome clinker and burned magnesite-iron clinker, MgO-CaO clinker, MgO-Cr2O3 clinker and so forth to meet with the requirement of internal and external markets. The raw material of high-purity magnesite is selected from natural super graced siderite, and is made through the processes of the floatation, purity, fine-grinding, briquetting and super high temperature calcining in oil shaft kilns. It is the excellent raw material for the brick making and the unshaped refractory material making. The medium magnesia and medium magnesia produced by our company has two types. Both magnesia contains light fired magnesia powder (MgO *5%**9%). They are fired and pressed to balls in vertical furnace (using oil). The products is goodly burned, and have high density. They are used as high-duty raw material in producing magnesia products.
