Thermal dehydration and vibrational studies of ZnK4(P 3O9)2·6H2O

Research output: Contribution to journalArticle

Abstract

The thermal dehydration of ZnK4(P3O9) 2·6H2O was studied in the range 25-500°C by thermogravimetric analysis (TGA and DSC) and X-ray diffraction. We found, based on the TGA and DSC scans, the dehydration of this salt takes place in three stages with a loss of the six water molecules. The infrared and Raman spectra of ZnK4(P3O9)2·6H2O have been recorded and interpreted using a factor group analysis. The internal modes are assigned in terms of POP and PO2 structural units using experimental and theoretical IR and Raman frequencies.
