2D plot of the diffraction pattern of temperature-dependent synchrotron diffraction measurements from 130 to 300 and 302–1070 K in a 2θ variety from 2° to 9.5° . The pattern in the temperature range among ∼450 and ∼575 K capabilities considerably reduced intensities due to beam fluctuations for the duration of the measurements. At temperatures above 800 K more reflections seem due to reactions of the material with the capillary.
