Medical Magnesium Carbonate Heavy

During the preparation of medical heavy magnesium carbonate, the main factors influencing the product are magnesium oxidecontent, bulk density, etc. Soda ash and brine as the raw material, the metathesis reaction after pyrolysis, separation, drying then get medical heavy magnesium carbonate. Concentration of reactants, reaction temperature and reaction time directly affects the quality of the products. The preparation technology of medical heavy magnesium carbonate, control the reactant concentration are (20～25)g*L－1 Mg2＋,(88～11)g*L－1NaCO3. Reaction temperature: Double decomposition reaction under normal temperature, pyrolysis temperature control at about 90 ℃. The reaction time is 3 ~ 4 h, drying temperature is about 100 ℃.

    Hebei Meishen Chemical Technology Co.,LTD is the professional pharmaceutical grade and food grade magnesium carbonate manufacturer in China. Metathesis using domestic unique production, twice purify by thousands of degrees of high temperature calcination to produce pharmaceutical grade magnesium carbonate. We have reached the EU standards, which is far better than the national pharmacopoeia standards. The quality of the finished product can effectively avoid accidents due to drug failure caused by substandard quality magnesium carbonate.
