In addition we have the latest versions of the International Centre for Diffraction (ICDD) databases , including the PDF-4 inorganic and PDF-4 organic databases that are used for identification of unknowns.
High-temperature in situ X-ray powder diffraction patterns were used to study the dehydration kinetics of natural talc with a size of 10–15 µm. The talc was annealed from 1073 to 1223 K, and the variations in the characteristic peaks corresponding to talc with the time were recorded to determine the reaction progress.

Therefore, we studied apatite crystallization in water by synchrotron in situ X-ray diffraction. Crystallization was conducted from calcium chloride (0.2 M) and sodium phosphate (0.12 M) at pH 12 where hydrogen phosphate is the dominant phosphate species and at 60 В°C to allow the synchrotron measurements to be conducted in a timely fashion. Following the formation of an initial amorphous A correlated electron diffraction, in situ neutron diffraction and dielectric properties investigation of poled (1-x)Bi 0.5Na 0.5TiO 3-xBaTiO 3 ceramics
