Graphical Abstract
Raman spectroscopy has been used to study the tellurate mineral kuranakhite. A comparison of the Raman spectra with that of tlapallite and xocomecatlite is made.
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+O6ν1 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+O6ν3 antisymmetric stretching mode. Sharp intense bands at 452 and 462 cm−1 are assigned to the Te6+O6ν4 bending mode. A comparison of the Raman spectra of kuranakhite with that of tellurate-containing minerals tlapallite and xocomecatlite is made in this article. Copyright © 2008 John Wiley & Sons, Ltd.
