XRPD pattern ( Fig. 8 c) shows an increase of the peak at 2ϑ = 22° and a decrease of the one at 14°, both relative to the spectrum of the sample annealed to 122 °C. Heating up to 160 °C produces a sample with smooth glassy surfaces broken by sharp holes

there have been numerous reports on OLZ polymorphism, there are no literature reports regarding preformulation studies to support the design of solid dosage forms containing OLZ. In this study, DSC, TG, and XRPD techniques were applied with the

diffraction pattern (XRPD) was collected at room temperature on an Ital-Structure θ/θ diffractometer, under the following condition: Ni-filtered Cu-Kα radiation (λ = 1.5418 Å); range 3° ≤ 2θ ≤ 40°; scan 0.04°; t = 2 s step −1 . The XRPD pattern was also

estimates of the abundance of the mineral phases were derived from the XRPD data, using the intensity of specific reflections, the density and the mass absorption coefficients of the elements for CuKα radiation for the minerals present. Corrections of the
