| 4. | Description | Abstract | The paper investigates a set of physico-chemical properties of glasses of the M2O–MPO3, M2SO4–MPO3 (M = Li, Na) systems and glasses of the same systems in which one alkali metal was replaced by another. All compositions were obtained using mortar technology in the manufacture of the initial charge. It was found that almost all the properties of the studied glasses differ slightly in their characteristics from the properties of glasses of similar compositions obtained using solid starting components. It is shown that the electrical properties of pure phosphate and phosphate-sulfate glasses with a commensurate volume concentration of the main current carriers, alkaline cations, are close, i. e. the presence of sulfate ions in mixed glass increases the electrical parameters insignificantly. The equivalent substitution of lithium cations for sodium cations in phosphate and phosphate-sulfate glasses is accompanied by a polychelic effect – a nonlinear change in electrical parameters, and in the phosphate-sulfate system (with a close volume concentration of current carrier ions) this effect is more pronounced. |
