应用
Magnesium oxide is used as a refractive material, which is physically and chemically stable at higher temperature. Magnesium oxide is a raw material for producing portland cement. It is also used in agricultural, chemical construction, environment al and other industrial applications. It is also used in medicine, colorimetry, industrial cables, heating elements, ceramics, spin-tunneling devices, and several other materials.
