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.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
