STRONTIUM TELLURIDE Chemical Properties,Usage,Production

Description

Strontium telluride has the molecular formula of SrTe and the molecular weight of 215.2238 g/mol. It can be prepared by heating the elements together in an inert atmosphere:
Sr+ Te+ heat ? SrTe
Te melts at 450 °C and Sr melts at 778 °C. A heating temperature of 750 °C is sufficient to cause complete reaction. SrTe powder can also be prepared by the reaction of stoichiometric quantities of Sr and Te in a pure graphite crucible in vacuum at 480 °C during 48 h. Its molecular weight is 166.58 g/mol. Strontium telluride has the CAS number of 12040-08-3. It is a white, crystalline solid with a density of 4.83 g/cm3. It has the rock salt structure with octahedral coordination of the Sr2+ cation. Its refractive index is 2.408. If heated to 1605 °C, it decomposes.
Pb1-xSrx Te films were prepared by hot-wall epitaxy on BaF2(111) substrates. X-ray diffraction analysis, optical transmission measurement, Hall measurement and EPMA were performed on the films. It was observed that the increasing rate of the lattice constant of the Pb1- xSrxTe films with the SrTe content was considerably larger than that estimated from Vegard’s law. Pb1-xSrxTe/PbTe double-heterostructure (DH) and multiple quantum well (MQW) lasers were also prepared for the first time by hot-wall epitaxy. Pulsed laser operations were obtained up to 227 K (4.1 μm) for the DH laser and up to 220 K (3.5 μm) for the MQW laser. Large output energy shifts due to misfit strain in the active layer were observed.
Strontium telluride is not used in industry for any purpose and the scientific literature concerning it has been very scattered.
