Diffraction scanning calorimetry
WebThe diffraction pattern was scanned over 0°–60° 2θ, at a scanning speed of 2° 2θ/min. The resulting X-ray powder diffraction pattern is shown in Fig. 1, where the compound is seen to be amorphous. Khatri et al. [21] used the X-ray powder diffraction pattern of cefpodoxime proxetil, in evaluation of the drug substance. WebAug 2, 2024 · After annealing at 650 °C, crystalline PuF4 and PuO2 remain. Thermogravimetric analysis and diferential scanning calorimetry—with simultaneous evolved gas analysis—of the separated PuF4-p and PuF4-b components reveal a distinct sequence of reactions. Dehydration occurs between~90 and 300 °C.
