The metal improves the mechanical, fabrication, and welding characteristics of aluminum when used as an alloying agent. Magnesium is used in producing nodular graphite in cast iron, and is used as an additive to conventional propellants. It is also used as a reducing agent in the production of pure uranium and other metals from their salts. Dead-burned magnesite is employed for refractory purposes such as brick and liners in furnaces and converters. Compounds Organic magnesium is important in both plant and animal life.
Chlorophylls are magnesium-centered perphyrins.
Handling Because serious fires can occur, great care should be taken in handling magnesium metal, especially in the finely divided state. Water should not be used on burning magnesium or on magnesium fires.
