Phase equilibria in the quasi-ternary system Ag2S–In2S3–CdS at 870 K

An isothermal section of the quasi-ternary system Ag2S–CdS–In2S3 at 870 K was investigated using X-ray phase analysis. No quaternary intermediate phase was found. A continuous solid solution series between In2S3, AgIn5S8 and CdIn2S4 was discovered; a limited solid solution range of CdS is localized along the AgInS2–CdS section.
