• 개요

  Bariumtellurate has the molecular formula of BaTeO4 and the molecular weight of 328.9742 g/mol. Barium tellurate has the molecular formula of BaTeO4 and the molecular weight of 328.936 grams per mole. Its CAS number is 13466-24-5 and its solubility in water is 0.727 g/100 ml at 20°C. It can be prepared by the solid-state reaction of TeO3 and BaO:
  BaO + TeO3 + heat ? BaTeO4
  TeO3 melts at 430°C and a temperature of 650°C serves to drive the reaction to completion. This is the tetragonal meta-tellurate composition. It can also be formed in the same manner by solid-state reaction of telluric acid:
  BaO(solid)+H2TeO4(solid) ? BaTeO4(solid) +H2O(gas)
