| Abstract: | A series of discrete copper sulphide phases have been identified during the anodic oxidation of Cu2S to CuS. The four intermediate phases, viz. Cu1.95–1.91S, Cu1.86–1.80S, Cu1.68–1.65S, and Cu1.40–1.36S, have been characterized by X-ray diffraction and in situ measurement of reflectance spectra. Their free energies have been calculated from the electrode potentials and compared with other work. |
