カルシウムテルリド 化学特性,用途語,生産方法
説明
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/cm
3. It has the rock salt structure
with octahedral coordination of the Ca
2+
cation. Its refractive index is 2.51. If heated to 1605°C, it decomposes.

使用
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.
