From: Coexistence of multiple metastable polytypes in rhombohedral bismuth
XRD patterns of various Bi samples as compared with those calculated from the new structural polytypes.
(a) Experimental XRD spectra corresponding to the Bi samples recovered from raw material, cold-pressing at 2GPa and 2.7GPa, HT-HP treating at 2GPa-1073K and 2GPa-2273K and the calculated XRD spectra of M, T1, T2 and A7 structures. (b) The enlarged spectra at the range of 26.5~27.5°.
