Abstract
The antimony-rich iridium antimony phase diagram was investigated by m eans of differential thermal analysis, microprobe analysis, metallogra phy and X-ray powder diffraction. The existence of three compounds was confirmed in the range 50-100 at.% Sb: IrSb3 which forms by peritecti c reaction at 1141-degrees-C, IrSb2 which also forms peritectically at 1475+/-30-degrees-C and IrSb which melts congruently at 1645+/-25-deg rees-C. IrSb3 forms a degenerate eutectic with antimony at 621-degrees -C. The shape of the liquidus line was also investigated.
