These regions are completely concentrated in the borate-rich region of the concentration triangle and occupy approximately 20% of the triangle area. The IR and Raman spectra of the glasses under investigation are recorded. It is revealed that the vibrational spectra of the glasses depend on the type of alkaline-earth metal cation. It is assumed that the structure of the glasses is determined by the glass-forming borate motifs with embedded sulfate anion tetrahedra. Полный текст |

Original synthesis processes for these compounds were developed; their thermal stability parameters were determined. Potassium and thallium(I) octavanadates were shown to form complete solid solutions with each other. Potassium octavanadate in air is stable to 450°C; above this temperature, it transforms, on account of partial reduction of vanadium, to vanadium bronze by the reaction K2V8O21<--> K2V8O20.8 + 0.1O2. The K2V8O20.8 percentage in the sample increases with rising temperature. The substitution of small thallium amounts for potassium (x ≥ 0.025) enhances the stability of the phase until it melts at ~525°C. Полный текст |
