MAGNESIUM



Magnesium is one-third lighter than aluminum and it improves the mechanical, 


fabrication, and welding characteristics of aluminum when used as an alloying 


agent. It is used for aerospace, satellite and missile construction. Magnesium 


compounds, primarily magnesium oxide, are used as refractory material in furnace 


linings for producing iron and steel, nonferrous metals, glass, and cement. High 


purity magnesium is found in dietary supplements. Magnesium is available as 


metal and compounds with purities from 99% to 99.999% (ACS grade to ultra-high 


purity). Elemental or metallic forms include pellets, rod, wire and granules for 


evaporation source material purposes. Magnesium oxide is available in powder 


and dense pellet form for such uses as optical coating and thin film applications. 


Oxides tend to be insoluble. Magnesium fluoride is another insoluble form for 

uses in which oxygen is undesirable such as metallurgy, chemical and physical 


vapor deposition and in some optical coatings. Magnesium is also available in 


soluble forms including magnesium chloride, magnesium nitrate, and magnesium 


acetate. These compounds can be manufactured as solutions at specified 


stoichiometries.
