Current status of product operation

Magnesium oxide (MgO) is a white, wet solid mineral and is considered as source of magnesium. Magnesium oxide consists of a network of Mg2+ ions and O2- ions, which are connected by ionic bonds.

Magnesium hydroxide is formed in the presence of water (MgO + H2O → Mg(OH)2), but this can be reversed by heating to remove the moisture. Magnesium oxide is produced by calcining magnesium carbonate or magnesium hydroxide.

Calcining at different temperatures produces magnesium oxide with different reactivity. High temperatures of 1500 to 2000 °C reduce the available surface and produce dead burnt magnesium (often called dead burn), which is a non-reactive form and is used as a refractory.

Calcining temperatures of 1000 to 1500 °C produce hard-burnt magnesia, which has limited reactivity, and calcination at a lower temperature (700 to 1000 °C) produces light-burnt magnesia, a reactive form known as magnesia.

Although some decomposition of carbonate to oxide occurs below 700°C, the resulting materials appear to reabsorb carbon dioxide from the air. This product is widely used in various fields and is used as a refractory brick in the steel industry.

Magnesia plants are used in super alloy industries, nuclear industries and chemical industries where corrosion resistance is required. Magnesia is also used as a room temperature curing agent for phosphate cements.

Magnesia powder is widely used as filler for electric heating elements for applications in contact with air or liquids. It is also used as mineral insulation in cables.

​​​​​​​ It is used in thermocouple tubes, brake pads, and plasma screens, and high purity magnesium is used to grow thin layer semiconductors. Magnesium oxide is used in medicine, pharmaceutical and food industry as an anti-inflammatory.
