Magnesium silicide (Mg2Si): ACTIVE
応用分野
説明Magnesium silicide has the molecular formula of Mg2Si and the molecular weight of 76.6955 g/mol. Its density is 1.998 g/cc and its melting point is 1102°C. It is a black powder.Mg2Si crystallizes in a cubic CaF2 (fluorspar)-type lattice with a = 4.49 . The centers of this lattice are analogous to that of diamond. Each Si atom forms four covalent sp3 bonds. The Mg subshells are only half-filled. There is no bonding between the two Mg atom sites. The distance between the Mg and Si atoms is 2.77 . Bonding in this compound is essentially covalent.
使用Magnesium silicide is used to produce alloys such as aluminum alloys. It is also used in food, beverages, as a flavor enhancer and as an intermediate in chemical research.
一般的な説明A colorless crystalline solid. Insoluble in water and denser than water. Contact may irritate skin, eyes and mucous membranes. May be toxic by ingestion.
