The dead burned magnesite is well-fired with a steady quality. It is a fine feeding matenal for manufacturing magnesia-base shaped products. The medium grade magnesite is made from super grade nature ore through a process of calcinations in reflecting kilns, hand-separating, fine mill, dry pressing under high pressure and high temperature sintered in shaft
kilns. The material is featured by high purity and fine micro-structure. It is a feeding material for making magnesia-based shaped refractory.
