PHASE RELATIONS IN THE Cu3SbS4-Sb2S3-S SYSTEM

Abstract

Phase relations in the Cu3SbS4-Sb2S3-S system were determined experimentally over the entire concentration range by means of differential thermal analysis (DTA) and powder X-ray diffraction (PXRD) techniques. One boundary, two internal polythermal sections, and the liquidus surface projection of the system were constructed. Primary crystallization fields of existing phases, as well as, types and coordinates of non- and monovariant equilibria were determined. It was defined that, the concentration triangle under study is an independent subsystem of the Cu-Sb-S ternary system and belongs to the monotectic type with a wide stratification field of two liquids.

POWDER X-RAY DIFFRACTION STUDY OF THE Cu3SbS3-CuI SYSTEM

“…The presented work is a continuation of our research [14][15][16][17][18] in the field of metal chalcogenides and chalco-halides and is dedicated to the study of phase equilibria in the Cu 3 SbS 3 -CuI system. Initial compounds of the system are well studied.…”
