Abstract

Phase identifications and quantitative analyses of mixed crystals by means of abrasive stripping voltammetry are reported using covelliteklockmannite (CuSxSe1-x) and emplectite-chalcostibite (CuBix Sb1-xS2) mixed crystals as examples. The composition of CuSxSe1-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.
