| Abstract: The title compounds were prepared through ion exchanges of Li+, Na+ and K+ with H+ of white powdery tungstic acid. Elemental analyses, IR and UV spectra show that the title compounds have a general formula, M3HW10O32·11H2O(M = NH4, Li, Na and K). The X-ray powder diffraction, thermal analyses, IR and UV spectra, stabilities in aqueous and non-aqueous solutions, and photochromism have also been studied. |
| Keywords: white powdery tungstic acid decatungstate ion exchange |
