  • Synonyms:

    Telluric acid (H2TeO4),calcium salt (1:1);Calcium tellurate (CaTeO4)

Description

Calcium tellurate has the molecular formula of CaTeO4 and the molecular weight of 231.68 grams per mole. Its CAS number is 712354-41-1 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 CaO: CaO + TeO3 + heat CaTeO4
TeO3 melts at 430 °C and a temperature of 600° C serves to drive the reaction to completion. This is the tetragonal meta-tellurate composition.
