Magnesium Oxide MGO

Magnesium oxide is an inorganic compound with the chemical formula MgO. It is an oxide of magnesium. It is a white solid at room temperature. It is odorless, tasteless and non-toxic. It is a typical alkaline earth metal oxide. It has highly fire-resistant insulating properties, with a melting point of 2852°C, a boiling point of 3600°C, and a density of 3.58g/cm³ (25°C). Magnesium oxide is insoluble in water and ethanol, but soluble in acid and ammonium salt solutions, and its solution is alkaline. When exposed to air, magnesium oxide easily absorbs moisture and carbon dioxide, and is gradually converted into basic magnesium carbonate.

Magnesium oxide has important applications in many fields. In the field of building materials, it can be used to produce magnesite products, such as magnesite cement. This new type of cement has the advantages of light weight, high strength, heat insulation and fire prevention, environmental protection and energy saving. In lubricating oil processing, magnesium oxide can be used as a detergent, vanadium inhibitor, and desulfurizer to improve the compactness and rheology of the lubricating film. In addition, magnesium oxide is also used as a food additive, color stabilizer, pH regulator in health products and foods, as well as an antacid, adsorbent, complex filter aid, etc. in the field of biopharmaceuticals.

When using magnesium oxide, you need to pay attention to its tendency to absorb moisture and carbon dioxide, which may cause its properties to change. Therefore, storage and use should be kept dry and avoid contact with moisture and carbon dioxide in the air.
