RESEARCH INTO PHASE FORMATION AND SOME PHYSICAL AND CHEMICAL PROPERTIES OF THE Sb2Se3-GaSe SYSTEM ALLOYS
Behavior of interaction in the Sb2Se3-GaSe system was explored and a phase diagram constructed using the complex methods of physical and chemical analysis: differential thermal (DTA), X-ray phase (XRD), microstructural analysis (MSA), as well as the measurement of micro hardness and density. It found that in the system Sb2Se3-GaSe two congruently melting compounds of the GaSb4Se7 and GaSb2Se4 compositions are formed at 515 ° C and 490 ° C, respectively. It revealed that the GaSe-based solubility in solid state is 4 mol. % Sb2Se3;but if based on Sb2Se3 - it is 5 mol. % GaSe. Three eutectics are formed in the system with composition appropriate of 43 and 60 mol. % Sb2Se3 and melts at 470, 425 and 450°C, respectively.
