칼슘텔루라이드 C화학적 특성, 용도, 생산

개요

Calcium telluride has the molecular formula of CaTe and the molecular weight of 167.6782 g/mol. It can be prepared by heating the elements together in an inert atmosphere:
Ca+ Te+ heat ? CaTe
Te melts at 450°C and Ca melts at 842°C. A heating temperature of 750°C is sufficient to cause complete reaction. CaTe powder can also be prepared by reaction of stoichiometric quantities of Ca and Te in a pure graphite crucible in vacuumat 480°C for 48 h. Its molecular weight is 119.04 g/mol. Calcium telluride has the CAS number of 12013-57-9. It is a crystalline solid with a density of 4.872 g/cm³. It has the rock salt structure with octahedral coordination of the Ca²⁺ cation. Its refractive index is 2.51. If heated to 1605°C, it decomposes.

화학적 성질

cub; -20 mesh 99.5% purity [CER91] [CRC10]

용도

CaTe has found very little usage in industry and the only available information academically deals with its usage to form ternary tellurides. It is available commercially in limited quantities.
