Thermal and vibrational studies of potassium selenate tellurate K_2SeO_4.Te(OH)_6

摘要

Telluric acid forms addition compounds with alkali sulphate and selenate while the two anions (AO_4~(2-) and TeO_6~(6-), where A=S, Se) exist almost independently in the crystal. Recently, we have study the structure of telluric acid and potassium selenate [1].
