| Popis: |
A study is presented of phase transitions of acid CaHPW12O40∙6H2O salt of 12-tungstophosphoric acid and characterized in the temperature range from room temperature to 1093 K. The structure and its phase transformations were characterized by thermal analysis (TGA and DSC), X-ray powder diffraction (XRPD) and Fourier-transform infrared spectra (FTIR). Dehydration processes are finished at about 770 K. Keggin’s anions are transformed by solid-solid recrystallization at about 873 K in calcium doped phosphate tungsten bronze. |
