Figure 3
(a) X-ray oscillation photographs of AlPO4-5 during a heating–cooling cycle. The upper-left panel shows the diffraction pattern at 298 K under atmospheric pressure together with its magnified view. The subsequent enlarged images to the right (upper row) were collected during heating under vacuum, while those in the lower row correspond to cooling under the same vacuum conditions. The lower-left panel shows the diffraction pattern after the heating–cooling cycle at 300 K. The powder rings observed in the vacuum measurements originate from scattering by the Kapton window and are absent in the ambient-pressure image. (b) Raman spectra measured at 298 K under atmospheric pressure and at 298 K, 310 K, and 320 K under vacuum. (c) Intensities of a satellite peak, 0211 reflection, recorded during the heating and cooling process. |
