![]() Magnesium compounds are used as refractory material in furnace linings for producing metals (iron and steel, nonferrous metals), glass, and cement. The main ingredients of the alloys are: aluminum, manganese, zircon, zinc, rare-earth metals and thorium. It was used for a long time for synthesizing special and complex organic components by the well-known Grignard reaction. Used as a catalyst, magnesium promotes organic reactions of condensation, reduction, addition and dehalogenization. Magnesium reacts only slightly or not at all with most of the alkalis and many organic substances, like hydrocarbons, aldehides, alcohols, phenols, amines, esters and most of the oils. It joins together with most non-metals and almost every acid. Magnesium is very chemically active, it takes the place of hydrogen in boiling water and a great number of metals can be produced by thermic reduction of its salts and oxidized forms with magnesium. Magnesium is known for a long time as the lighter structural metal in the industry, due to it’s low weight and to it’s capability of forming mechanically resistant alloys. Its relative density is 1,74 and it’s density 1740 kg/m 3 (0.063 lb/in 3 or 108.6 lb/ft 3). Magnesium is silvery white and very light.
