PHYSICAL PROPERTIES
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral that occurs naturally as periclase and is a source of magnesium . It has an empirical formula of MgO.Pure MgO is not conductive and has a high resistance to electric current at room temperature.
Uses:
Magnesium oxide has many uses and is widely used in building materials, municipal administration, agriculture, machinery and other fields.
1. In the building materials industry, magnesium oxide is used to produce magnesium cement. This new type of cement has the advantages of light weight, high strength, heat insulation and fireproof, environmental protection and energy saving.
2. Fireproof. As a building material, magnesium oxide wallboard has several attractive properties: fireproof, termite-proof, moisture-proof, mildew-proof and strength.
3. Magnesium oxide is widely used in soil and groundwater remediation, wastewater treatment, drinking water treatment, air emission treatment and waste treatment industries due to its acid buffering capacity and related efficacy of stable dissolution of heavy metal substances.
4. It can also be used as a raw material for the manufacture of ceramics, enamel, refractory bricks, etc.
5. In the chemical industry, magnesium oxide is used as a raw material to produce magnesium sulfate, magnesium hydroxide, magnesium chloride, etc.
6. In the food industry, magnesium oxide can be used as a decolorizer when refining sugar, a pH adjuster for ice cream powder, and an anti-caking agent and antacid in wheat flour, milk powder, chocolate, cocoa powder, grape powder, powdered sugar and other agents.
7. Medical treatment. Magnesium oxide is used to relieve heartburn and indigestion as an antacid, magnesium supplement, and short-term laxative. It is also used to improve symptoms of indigestion.
