Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): ФТОРСУЛЬФАТНЫЕ СТЕКЛА -- БИНАРНЫЕ СИСТЕМЫ -- ЛИТИЙ Аннотация: The glass-forming ability is investigated in the LiF–ZnSO4 binary system. It is found that, upon cooling melts at a rate of 103K/s, the glass formation is observed in the concentration range 30–60 mol % ZnSO4 . The characteristic temperatures are determined using differential thermal analysis. The density of glasses is measured by hydrostatic weighing. The experimental results obtained are used to calculate the molar volumes and the thermal stability parameters of lithium-containing fluorosulfate glasses Полный текст |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): СТРУКТУРА СТЕКЛА -- ЯМР -- СТЕКЛА ФОСФАТНО-СУЛЬФАТНЫЕ Аннотация: The structure of sulfate–phosphate glasses is investigated by high-resolution 31P solid-state nuclear magnetic resonance with magic-angle sample spinning (31P MAS NMR spectroscopy). The structure parameters that account for the number of different types of phosphorus–oxygen structural units involved in the glass network are determined, and the main structural units of the glasses under investigation are revealed. The role of H2O and Na2SO4 as modifiers of the structural network of sulfate–phosphate glasses is clarified Полный текст |

Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): СТЕКЛА -- СУЛЬФАТ ЦИНКА -- ФТОРИД НАТРИЯ Аннотация: The glass-forming ability is studied in the NaF–ZnSO4 system. It is revealed that, when melts are cooled at a rate of 103 K/s, the glass formation is observed in the concentration range 35–70 mol % ZnSO4. The characteristic temperatures are determined by differential thermal analysis. According to these temperatures, fluorosulfate glasses can be assigned to low-melting glasses. The density of glasses is measured by hydrostatic weighing. The experimental data obtained are used to calculate the molar volume and the thermal stability parameters of fluorosulfate glasses Полный текст |
