Light burned magnesium and heavy burned magnesia (brucite bitter soil) can be prepared by calcining brucite at high temperature. If lithium hydride or lithium fluoride is further mixed, pressed into pellets with a diameter of 40 ~ 60 mm, and then put into smelting, magnesium agent and rare earth catalyst are added in the smelting process, high-purity magnesia can be obtained.
Brucite and dolomite are calcined into magnesium and calcium oxides at high temperature, then ground, mixed with organic binder, pressed into a mold, and the refractory brick can be prepared after secondary calcination. This kind of refractory brick can replace magnesia high temperature refractory brick in metallurgical industry.
