Magnesium oxide (MgO) is a white solid at room temperature and exists in nature as periclase. It can be produced by calcining basic magnesium carbonate or magnesium hydroxide, or using carbon dioxide as an oxidant. Magnesium oxide is slightly soluble in water and soluble in acid. It has a wide range of applications, such as refractory materials, enamel, polishing agents, adhesives, paints, etc. It can also be used for radio high-frequency magnetic rod antennas instead of ferrite and to make refractory fibers and other refractory materials.
