Magnesium Oxide with high purity/MgO


Magnesium oxide (chemical formula: MgO) is an oxide of magnesium, an ionic compound. At room temperature, it is a white solid. Magnesium oxide exists in the form of periclase in nature and is a raw material for magnesium smelting. White fine powder. No odor. Due to different preparation methods, there are light and heavy types. Has strong refractive index in the visible and near ultraviolet light range.
Magnesium oxide powder exposed to the air is prone to absorb moisture and carbon dioxide, gradually becoming basic magnesium carbonate. It is lighter than heavier and reacts faster with water to form magnesium hydroxide, exhibiting a slightly alkaline reaction. The pH of the saturated aqueous solution is 10.3. But it is highly soluble in dilute acid and slightly soluble in pure water, increasing its solubility due to the presence of carbon dioxide. Insoluble in ethanol. Relative density (d254) 3.58. The melting point is 2852 ℃. Boiling point is 3600 ℃.
