MAGNESIUM ANTIMONIDE Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Its molecular weight is 316.4351 g/mol. Mg₃Sb₂ melts at 1245°C. Structural stabilities elastic properties and electronic structures have been determined from first-principles calculation by using Castep and Dmol computer programs based on the density functional theory given for the Mg₃Sb₂ phase. The calculation results of heat of formation and cohesive energy indicate that Mg₃Sb₂ has a strong alloying ability as well as the highest structural stability of those compounds studied.

• Beschreibung

  Magnesium antimonide has been prepared by the reaction of Mg and Sb metals. Mg melts at 652°C and is stable in an inert atmosphere until its boiling point of 1091°C is reached. Since Sb melts at 630.6°C and is stable in an inert atmosphere until its boiling point of 1587°C, the reaction is best carried out by evaporating Mg metal at about 680°C onto molten Sb metal.

• Chemische Eigenschaften

  hexagonal; 6mm pieces and smaller with 99.5% purity [CER91] [CRC10]

• Physikalische Eigenschaften

  Its molecular weight is 316.4351 g/mol and its CAS number is 12057-75-9. Mg₃Sb₂ melts at 1245°C. Structural stabilities elastic properties and electronic structures have been determined from first-principles calculation by using Castep and Dmol computer programs based on the density functional theory given for the Mg₃Sb₂ phase.

• Verwenden

  Magnesium antimonide has also been used in an electrochemical and device apparatus for high-amperage electrical energy storage. It features a hightemperature, all-liquid chemistry. The batteries are simply tanks filled with three separate layers of liquid that float on top of one another at 700°C: the top layer is molten magnesium, the bottom is antimony, and the middle layer is a salt containing magnesium antimonide, a dissolved compound of the two metals.
