Magnesium Oxide Powder (MgO, 99.5%)

Magnesium Oxide Powder

Introduction:

Magnesium oxide powder is an inorganic compound that consists of magnesium and oxygen. It is a white, odorless, and fine powder that is highly stable, non-toxic, and has a high melting point. Magnesium oxide is commonly known as magnesia and is produced by heating magnesium carbonate (MgCO₃) or magnesium hydroxide (Mg(OH)₂) at high temperatures, a process known as calcination.

Applications:

In Refractories and Ceramics:

Refractory Materials: Magnesium oxide is widely used in the manufacture of refractory materials due to its high melting point and thermal stability. MgO is an essential component of refractory bricks and castables used in high-temperature industrial processes like steel production, cement kilns, and furnaces. Its thermal resistance and chemical stability make it an ideal material for lining high-temperature kilns, furnaces, and reactors.

Ceramic Glazes: MgO is used in ceramic glazes to improve durability and resistance to thermal shock, making it valuable in the production of porcelain, earthenware, and other ceramic products.

In Pharmaceuticals and Healthcare:

Antacid: Magnesium oxide is widely used as an antacid in the treatment of gastroesophageal reflux disease (GERD) and indigestion. It helps neutralize stomach acid and provides relief from heartburn and acid reflux.

Laxative: MgO is used as a laxative to treat constipation. It works by drawing water into the intestines, promoting bowel movements.

Magnesium Supplements: MgO is also used in magnesium supplements for individuals with magnesium deficiency. It is an excellent source of magnesium, an essential mineral for various bodily functions, including muscle function, nerve transmission, and bone health.

In Construction and Building Materials:

Cement and Concrete: Magnesium oxide is used in the production of magnesium-based cements such as Magnesium Oxychloride Cement (MOC) and Magnesium Oxysulfate Cement (MOS). These cements offer fast-setting properties, high strength, and low environmental impact compared to traditional Portland cement. They are used in applications such as flooring, coatings, and building facades.

In Electronics and Electrical Applications:

Insulating Material: Magnesium oxide is used as an electrical insulator in high-voltage and high-temperature applications. It is commonly used in the manufacturing of electrical cables and wires, where it helps to prevent short circuits and protect conductors from heat.

Thermal Insulation: MgO is often used in thermal insulation for components like heaters and electric furnaces, as it helps to retain heat and improve energy efficiency.
