Abstract
Conditions for obtaining of quasi-binary salt system (Na2SO4)1-х(Gа2(SO4)3)х are developed and the length of the region of its homogeneity is defined (х 0.00-0.07). The solid electrolyte (Na2SO4)1-х(Gа2(SO4)3)хis first synthesized, its conductivity by cations of gallium (III) is found. In the composition range 1.0-9.0 mol.% of (Gа2(SO4)3)х and the temperature range 373-723 K transport properties are investigated: electric conductivity, numbers of the electron transport, the diffusion coefficients of gallium (III) cations. The possibility of using a solid electrolyte (Na2SO4)0,95(Gа2(SO4)3)0,05 in the composition of an electrochemical cell for coulometric titration of lead telluride (Pb1±δTe) is shown, temperature range 553-673 K of its operation is determined.
