Epsom Salts Monorail Epsom Salts Monorail The Epsom Salts Monorail or Magnesium Monorail was a short-lived Lartigue Monorail in San Bernardino County, California, in the United States. It was built to carry epsomite (hydrated magnesium sulphate) from a deposit in the Owlshead Mountains to a siding of the Trona Railway. It ran nearly due east from Trona, for a distance of about . The monorail was opened in 1924 and closed in June 1926. Thomas Wright, a florist from Los Angeles, set-up a camp in Crystal Hills Wash in 1918 and prepared an area for salt mining, where he had previously found some
Magnesium silicide Magnesium silicide Magnesium silicide, MgSi, is an inorganic compound consisting of magnesium and silicon. It can be produced by heating silicon dioxide, SiO, found in sand, with excess magnesium. The process first forms silicon metal and magnesium oxide, and, if an excess of magnesium is used, the silicide is formed: If an excess of Mg is present, MgSi is formed from the reaction of the remaining magnesium with the silicon: These reactions proceed exothermically. Magnesium silicide is used to create aluminium alloys of the 6000 series, containing up to approximately 1.5% MgSi. An alloy of this group can be age-hardened
