Abstract

The quasi-binary system FeSe–In2Se3 was re-examined by the methods of DTA and XRD and its T–x phase diagram was constructed. It was established that the diagram is somewhat different from the earlier one given by us in the literature. FeIn2Se4 compound, which congruently melts at 1195 K, was found in the system. This compound forms eutectics with both the initial binary compounds. The crystal structure of FeIn2Se4 is refined by using the powder diffraction data by the Rietveld method
