Magnesium oxide (chemical formula: MgO) is an important inorganic compound, typically appearing as a white powder or a solid block. It features a high melting point, high chemical reactivity, and excellent heat resistance, and is widely used in numerous fields. The production of magnesium oxide mainly involves calcination of ore or chemical synthesis methods, resulting in a product with high purity and stability.
(1) High Melting Point
Magnesium oxide has a melting point as high as 2800ºC, which endows it with outstanding high-temperature resistance, making it suitable for various applications in high-temperature environments.
(2) High Chemical Reactivity
Magnesium oxide is highly chemically reactive and can react with a variety of acids, bases, and salts. It is widely used in chemical reactions and material preparation.
(3) Good Heat Resistance
Magnesium oxide remains stable at high temperatures and is not prone to decomposition, making it suitable for the preparation of high-temperature materials and refractory materials.
