Magnesium oxide (chemical formula: MgO) is a tasteless, non-toxic ionic compound. It occurs naturally as the mineral periclase and is widely produced by calcining magnesium carbonate or magnesium hydroxide.
It is insoluble in water and ethanol, but soluble in dilute acids and ammonium salt solutions. As a strong electrolyte, MgO conducts electricity well in its molten state by releasing Mg²+ and O²- ions, while it is an electrical insulator in solid form.
With high melting point, good thermal stability and alkaline properties, magnesium oxide is extensively used in refractory materials, rubber, plastics, environmental treatment, pharmaceuticals and food additives.
