Magnesium powder is inflammable and explosive. It gives out temperature and dazzling white light when burning. So it's been widely used in military aerospace and other scientific and technological fields. Because of its active chemical characteristic, magnesium is usually used in metallurgy industry: it is used as dioxidizing agent and purifying agent in steelmaking and non-ferrous metal casting, and as dehydrating for organic compounds. Magnesium powder can also be used directly for organic compounds of magnesium. Especially in recent years, magnisium has been used more and more in spray coating and preservation industries. It is also used a lot in monocrystalline silicon directly olycrystalline silicon producing and metallurgy powder die-casting industry.
