Magnesium Oxide Applications

Learning about Magnesium Oxide
Magnesium oxide (MgO), or magnesia, is a white hygroscopic solid mineral used across various industries. MgO's unique properties make it an invaluable substance in numerous applications. Let’s explore these uses ranging from myriad health benefits to heavy industriesits.
Magnesium oxide, or MgO, is a white, inorganic compound that occurs naturally as it periclase. In its pure form, it is a fine powder with hygroscopic properties. That means it is capable of absorbing moisture from the air. This compound is produced industrially by the calcination of magnesium carbonate or magnesium hydroxide.

Health Applications
1. Dietary Supplement:
Magnesium oxide is crucial for correcting magnesium deficiency. Mg is associated with muscle spasms, cardiovascular diseases, and metabolic disorders.
Magnesium is essential for over 300 enzymatic reactions in the body, including those involved in energy production, DNA synthesis, and protein synthesis.
2. Digestive Health:
MgO acts as an effective antacid. It provides quick relief from heartburn and indigestion by neutralizing stomach acid.
It is also used as a laxative. This useful laxative works by drawing water into the intestines to soften stools and promote regular bowel movements.
3. Therapeutic Potential:
Emerging research suggests magnesium oxide may help manage migraines and alleviate symptoms of depression.
MgO is useful in cardiovascular health, particularly in managing hypertension and preventing conditions such as eclampsia in pregnant women.

Refractory Material Applications:
Magnesium oxide has an extremely high melting point of 2800 degrees Celsius. Thus, it is ideal for lining furnaces in the metal and glass production industries. This advanced material extends furnace life and enhances energy efficiency.

Environmental Management Applications:
Magnesium oxide acts as a neutralizing agent in water treatment processes. It adjusts the pH of industrial wastewater, so the wastewater turns safer for disposal or reuse. It also absorbs heavy metals and other pollutants from emissions, reducing environmental pollution consequently.

Construction Industry Applications:
Magnesium oxide is used to make MgO wallboard. Such wallboard is both fire-resistant and resistant to mold and mildew, so it is suitable for use in damp environments. When added to cement, magnesium oxide helps prevent cracking by absorbing excess moisture and enhances the durability of concrete structures.
