Hebei Messi Biology Co., Ltd. stated that anhydrous magnesium carbonate (MgCO3) is a single crystal of MgCO3 orthosalt. It mainly exists in the form of magnesite in nature and belongs to the calcite structure and trigonal crystal system. Because anhydrous magnesium carbonate has the advantages of high thermal decomposition temperature, large heat absorption, decomposition to
Hebei Messi Biology Co., Ltd. stated that basic magnesium carbonate is an important inorganic chemical product and has wide applications in modern society. With the acceleration of the modernization process, the demand for basic magnesium carbonate in countries around the world has increased. Existing products can no longer meet the growing demand, and it is
