a Selected XRD patterns during heating (FBRD10). The heating rate was 30 K/min. The vertical bars indicate peak positions calculated for bridgmanite under ambient conditions. The numbers are Miller indices. Pe, periclase. b Magnified XRD pattern of the near amorphous halo that appeared at a 2θ range of 3–20°. The amorphous halo signal from the glass capillary was subtracted, taking background measurements into account
