Abstract

Tellurates are rare minerals as the tellurate anion is easily reduced to the tellurite ion. An example of a tellurate containing mineral is kuranakhite. Two bands at 617 and 686 cm-1 are observed and assigned to the Te6+O6 ν1 symmetric stretching mode. The observation of two bands suggests the non-equivalence of the Te6+O6 in the structure. The broad band centred at 743 cm-1 is attributed to the Te6+O6 ν3 antisymmetric stretching mode. Sharp intense bands at 452 and 462 cm-1 are assigned to the Te6+O6 ν4 bending mode. A comparion of the Raman spectra of kuranakhite with that of tellurate containing minerals tlapallite and xocomecatlite is made.
