Investigation of the tellurium-rich part of the ternary system Ag-Nb-Te using A solid silver electrolyte
Abstract The binary system Ag-Te has been reinvestigated at temperatures between 500 and 630 K according to the work of Wagner et al.1. The solubility limit of silver in tellurium at 600 K has been found to be 0.7 mol-%. The application of the galvanostatic intermittent titration technique to the ternary system Ag-Nb-Te is shown by using appropriate solid state galvanic cells. Initial results show that constant cell voltages can be measured within a large three-phase area, consisting of a new Ag x Te-phase (with x ∼1.5), a NbTe y -phase (with y ∼4 and Te(+0.7 mol-% Ag).
