Applications of Magnesium Oxide

There are many different applications of magnesium oxide.

Refractories

Magnesium include has always been a source for making refractory brick in the steel industry. The ceramic material is typically impregnated with carbon materials, such as tar, pitch, or graphite to enhance the properties of the finished material, especially against corrosion in environments of basic slags.

Magnesia bricks are widely used in combination with spinel or chrome in ferroalloy, non-ferrous, glass and cement manufacturing industries.

Crucibles

Magnesia crucibles are used in the superalloy, nuclear industry, and chemicals industries to mitigate the corrosion of the substance. Magnesium crumbles often come in different purity grades. The addition of additives is used to promote sintering or restrict crystal growth. This includes clay, yttria, alumina, etc., depending on the application.  Magnesium crucibles are generally stable in high temperatures. The temperature ranges from 1400-2400 degrees Celsius.

Brake Linings

Because of its electromechanical properties, magnesia is also used in brake linings. Its intermediate hardness ensures that the wear on metal remains sufficiently low while conducting heat from the friction contact surfaces.

Plasma Display Screens

Magnesia is used in making the protective film that covers plasma display screens. In this case, the electro-optical properties of magnesium oxide are exploited.

Thermocouple Tubes

Extruded magnesia protective sheaths have been produced and used to provide a protective covering to thermocouples in aggressive conditions.

Heating Elements

Magnesia powder is a very important component in heating elements. It is used as a filling for electrical heating elements for use in contact with air or liquids. Fused magnesia gives you the best electrical resistance and thermal conductivity. The MgO forms a layer between the element and the outer sheath. It also serves as mineral insulation in cables.

When used as a secondary flux in high-temperature glazes, magnesium oxide melts well and can be present in glossy glazes.

Thin Film Formation

Magnesium oxide has been investigated for many electronic applications. High purity grades of magnesium oxide are useful for growing thin-film semiconductors.

Magnesium Cement

Magnesia cement is a binder used in refractories. The cement composition is based on the formulation of magnesium oxychloride. The cement is pretty fast-hardening and has several refractory and general repair applications.

one of the most important applications of magnesium oxide.

Magnesium oxide, otherwise known as magnesium, is an important ceramic material composed of magnesium and oxide. It’s known for its high thermal conductivity and strong corrosion resistance. Magnesium oxide is useful in several applications, such as refractory, crucibles, thermal engineering, and testing elements.
