BARIUM TELLURIDE Chemische Eigenschaften,Einsatz,Produktion Methoden

• Beschreibung

  Barium telluride has the molecular formula of BaTe and the molecular weight of 264.9270 g/mol. It can be prepared by heating the elements together in an inert atmosphere:
  Ba+ Te+ heat ? BaTe
  Te melts at 450°C and Ba melts at 728°C. A heating temperature of 750 Cis sufficient to cause complete reaction. BaTe powder can also be prepared by reaction of stoichiometric quantities of Ba and Te in a pure graphite crucible in vacuum at 480°C during 48 h. Its molecular weight is 216.31 g/mol. The heat of formation, △H⁰ at that temperature is 9.29 kJ/mol. Barium telluride can also be prepared by direct reduction of barium tellurate.

• Verwenden

  Barium telluride has been sadly overlooked in industry but not as a research subject in the literature. According to early sources, BaTe ought not to exist but a few workers have found methods to prepare it.However, the physical data such as melting point for this compound have not been available. It is, however, readily available commercially.
