Magnesium oxide (MgO) is widely used across multiple industries for its chemical stability, high-temperature resistance, and versatility.
- Food and Health: MgO acts as an anti-caking agent in powdered foods, preventing clumping by absorbing moisture. It is found in dietary supplements and antacids, providing a source of magnesium for human health. MgO also helps balance body acidity and relieve symptoms of acid reflux and indigestion[1].
- Industrial Manufacturing: Its high melting point makes MgO ideal as a refractory material in furnaces and kilns, particularly in steel, glass, and ceramics production. MgO is also an ingredient in cement and used as an electrical insulator in electronics[1][4].
- Environmental Applications: MgO is used in water and wastewater treatment, where it adsorbs heavy metals and neutralizes acids. It aids in soil remediation by stabilizing contaminated soils and capturing heavy metals. Additionally, it is used in flue gas scrubbing to remove sulfur dioxide emissions[2].
- Agriculture: MgO is supplemented in animal feed to promote bone growth and enzyme function in livestock. It also serves as a fertilizer component to enrich soils with magnesium[3][4].
- Medicine: Beyond antacids, magnesium oxide is used in pharmaceuticals to manage magnesium deficiency, aid in migraine prevention, and support certain cardiovascular and pregnancy-related conditions[1][3].
- Advanced Ceramics & Technology: MgO is a crucial component in high-performance ceramics and superconductors, optical materials, catalysis, spin-tunneling devices, and insulators for electronic applications[1][3][5].
- Other Uses: It is used as an optical material, white pigment, pressure transmitting medium in scientific equipment, and as a deacidification agent for preserving paper and books[5].
