| | MAGNESIUM ANTIMONIDE Basic information |
| | MAGNESIUM ANTIMONIDE Chemical Properties |
| | MAGNESIUM ANTIMONIDE Usage And Synthesis |
| Description | 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. | | Description | 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. | | Chemical Properties | hexagonal; 6mm pieces and smaller with 99.5% purity [CER91] [CRC10] | | Physical properties | 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. | | Uses | 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. | | Preparation | 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. |
