Magnesium oxide
基本信息
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. |
备注 | It is a hygroscopic solid, and reacts with water to form magnesium hydroxide, which can be converted back to magnesium oxide by heating to remove water. It is thermally stable up to about 700 K. |
