The quantitative analysis of mixed crystals CuS(x)Se(1-x) with abrasive stripping voltammetry and a redetermination of the solubility product of CuSe and the standard potential of the Cu/CuSe electrode.
Phase identifications and quantitative analyses of mixed crystals by means of abrasive stripping voltammetry are reported using covelliteklockmannite (CuS(x)Se(1-x)) and emplectite-chalcostibite (CuBi(x) Sb(1-x)S(2)) mixed crystals as examples. The composition of CuS(x)Se(1-x) can be determined within a span of x=+/-0.03. Additionally the standard potential of the Cu/CuSe-electrode is measured to be E(. )(Cu/CuSe)= -0.749 V vs. Ag/AgCl.
