Magnesium oxide - Food grade

About Magnesium oxide - Food grade

Magnesium oxide (MgO) is a chemical compound composed of magnesium and oxygen. Here are some key points about MgO: Properties- High melting point: MgO has a high melting point of around 2800C.- Refractory material: Due to its high melting point, MgO is used as a refractory material in furnaces and other high-temperature applications.- Basic oxide: MgO is a basic oxide, meaning it reacts with acids to form salts and water. Applications- Refractories: MgO is used in refractory bricks, castables, and other products for high-temperature applications.- Agriculture: MgO is used as a soil amendment to improve soil pH and provide magnesium nutrients to plants.- Pharmaceuticals: MgO is used as an antacid and laxative in some pharmaceutical products.- Electrical insulation: MgO is used as an electrical insulator due to its high electrical resistivity. Production- Calcination: MgO is often produced by calcining magnesite (MgCO3) or other magnesium-rich minerals.- Synthetic production: MgO can also be produced synthetically through various chemical reactions.
