Magnesium Oxide


Magnesium oxide, also known by its chemical formula MgO, is a white, odorless, and tasteless compound. It is an inorganic substance that occurs naturally as the mineral periclase. Magnesium oxide is produced through the thermal decomposition of magnesium carbonate or magnesium hydroxide. It is widely used in various industries due to its remarkable properties. In terms of physical properties, magnesium oxide is a solid with a high melting point of approximately 2,800 degrees Celsius. It is insoluble in water but can dissolve in acids to form magnesium salts. This compound possesses a cubic crystal structure and exhibits good thermal conductivity, making it useful in thermal insulation applications. Magnesium oxide is known for its high refractory properties, meaning it can withstand extremely high temperatures without melting or decomposing. This makes it an essential component in refractory bricks and linings for furnaces, kilns, and other high-temperature industrial processes. Moreover, magnesium oxide has excellent electrical insulating properties, making it suitable for electrical applications. It is commonly used as an insulator in electrical cables and wires to prevent electrical leakage and maintain safety. Additionally, magnesium oxide finds applications in the pharmaceutical and healthcare industries. It is used as an antacid to relieve symptoms of heartburn, indigestion, and acid reflux. Furthermore, it is an essential ingredient in some medications and dietary supplements. In summary, magnesium oxide is a versatile compound with a wide range of applications. Its high refractory and electrical insulating properties make it indispensable in various industries. Whether it’s used in refractory materials, electrical insulation, or as an antacid, magnesium oxide plays a crucial role in many aspects of our daily lives.

What are the differences between Magnesium Oxide and Magnesium Bisglycinate?

Magnesium Oxide is a common form of magnesium supplement that has a high magnesium content, but poor absorption rate. On the other hand, Magnesium Bisglycinate is a form of magnesium that offers better absorption and bioavailability, leading to the benefits of Magnesium Bisglycinate being more easily utilized by the body.
