The pharmaceutical industry extensively uses our Light Magnesium Oxide to make varied antacid medicines. It is effectively and carefully formulated using hydrated magnesium oxide, whose MgO content varies between 98 to 100.5%. 1309-48-4 is the CAS No. and 40.30 is the molecular weight of this magnesium oxide. Moreover, the offered Light Magnesium Oxide is alternatively called magnesium oxide and magnesia in the scientific language. It comes in a white, light, and fine powder, whose melting point is 2800 degree Celsius or 5072-degree fahrenheit. In addition, this magnesium oxide holds a pH level between 9.5 to 10.5. It can also be used as a reinforcing and filling agent in the rubber and plastic industrial applications.
