Abstract

Phase equilibria in the copper-cobalt-sulfur system have been determined by means of silica tube techniques between 400° and 900°C. Throughout this interval the Cu_2-xS solid solution containing up to 11 wt % Co, coexists with cobalt sulfides (CoS₂, Co₃S₄, Co_1-xS, Co₉S₈, Co₄S₃). Co₃S₄ accepts up to 20.5 wt % copper and CoS₂ up to 12 wt % copper into solid solution. The increase in unit cell dimensions of Co₃S₄ and CoS₂ when copper substitutes for cobalt has also been determined.
