Abstract

Phase relations were determined in the Cu-Sb-Se phase system at 300°, 400°, 450°, 500°, 600° and 700 °C. Five three-component phases are present at 300 °C: permingeatite (Cu3SbSe4), phase A (Cu3SbSe4, the Se-equivalent to skinnerite Cu3SbS3), phase B (CuSbSe2, the Se-equivalent to chalcostibite CuSbS2), phase C (Cu10.53Sb33.78Se55.68) and phase D (Cu38.8Sb6.10Se55.1). An X-ray crystallographic study is currently in progress on phase C. Phase D is present in insufficient amounts for such a study. At 400 °C phase C and D does not exist and at 500 °C all solid ternary phases are absent. At 450 °C two liquid fields exist in the Se rich portion of the phase diagram. At 500 °C they have united into one field. At 600 °C another liquid field has developed in the Sb-rich portion of the phase diagram, and at 700 °C only one field exists. It dominates the Se-Sb rich portion of the phase diagram. The maximum content of Sb in Cu-Se phases, Cu in Sb-Se phases and Se in Cu-Sb phases has been studied in detail.
