Synthesis and stability of single-phase chalcopyrite – a

Abstract. Single-phase chalcopyrite (CuFeS 2) is a key reference material in the development of new metallurgical processes to ensure a reliable copper supply.Here, we report on the successful synthesis of single-phase chalcopyrite and its phase behaviour. We further rationalise different opinions previously expressed in the literature.
