We investigated the phase diagram in bismuth at high pressures and high temperatures using the multi-anvil press and the synchrotron X-ray diffraction technique. The stability of each phase was identified by observing the powdered X-ray diffraction data. The phase diagram determined in our study was in general agreement with that reported in previous high-pressure experiments. However, discrepancies related with triple points were identified between present and previous studies.
