MAGNESIUM OXIDE POWDER AND INDUSTRIAL APPLICATIONS

1. What is Magnesium oxide?

Magnesium Oxide is an oxide compound of magnesium and belongs to the group of alkaline earth oxides with the chemical formula MgO. This chemical exists in solid form with white powder, odorless and soluble in water, acids, ammonia but insoluble in alcohol.

Magnesium Oxide is also known by different names such as Magnesium Oxide, Magnesia, Magnesium oxide.

Magnesium Oxide is widely used in many industries from ceramic production, building materials, heat-resistant furnaces to medicine.
