Magnesium oxide

About Magnesium oxide

Magnesium oxide (MgO), also known as magnesia, is a white, hygroscopic (moisture-absorbing) solid mineral. It occurs naturally as the mineral periclase. Its an inorganic compound formed by the chemical bonding of magnesium and oxygen. MgO is known for its high melting point, high heat capacity, and ability to neutralize acids. Key Properties: Appearance: White, odorless powder. Chemical Formula: MgO. Occurrence: Naturally found as the mineral periclase. Bonding: Ionic bonding between magnesium (Mg) and oxygen (O) ions. Melting Point: 2852C (5166F). Boiling Point: 3600C (6473F). Solubility: Soluble in acids and ammonia, slightly soluble in water, and insoluble in alcohol. Basic Nature: Magnesium oxide is a basic oxide, meaning it reacts with acids. Uses: Refractory Material: Used in furnace linings and other high-temperature applications due to its heat resistance. Antacid: Used to relieve heartburn and indigestion by neutralizing stomach acid. Laxative: In higher doses, it can act as a laxative by drawing water into the intestines. Dietary Supplement: Used to treat or prevent magnesium deficiency. Catalyst: Used in various chemical reactions due to its basicity and redox properties. Insulating Material: Used in electrical heating elements and other insulating applications. Fireproofing: Used as a fire-resistant component in construction materials. Colorimetry: Used as a reference white in colorimetry due to its reflectivity.
