Uses of Magnesium Powder
Magnesium powder is widely used in aviation, aerospace, armaments, automobiles, petroleum, chemicals, pharmaceuticals, smelting, and other industries.
Magnesium powder is flammable and explosive, and produces high temperature and dazzling white light when burned. Therefore, magnesium powder is widely used in scientific and technological fields such as the military industry and the aerospace industry. In the steelmaking industry and non-ferrous metal casting, magnesium powder is used as a desulfurizer and purifier, and as a reducing agent in the production of rare metals.
