Using X-ray diffraction data, the glassy phase of the manufactured glass systems is displayed in Fig.2. The XRD analysis demonstrated the complete amorphous nature of each glass sample and the absence of a uniform atom arrangement that would have been present in a crystal case. Due to variatio...
Bragg's equation shows the corresponding V 2O5 found in the XRD pattern (Fig. 1b). Differential Scanning Calometry (DSC) Figure 2 shows DSC thermogram of 60V2O5-15P2O5-25Bi2O3 glass that exhibits an exother- mic peak corresponding to crystallization (Tc) and an 13 ...
(step time: 1s; 2θ range: 5.0–90). The sizes of particles within as-synthesized samples were estimated using Debye-Scherrer’s equation, which was applied to the most intense peak observed in the XRD patterns. The surface functional groups of the as synthesized samples were identified after...
Its single crystalline nature has been revealed by the electron diffraction pattern (ED). Furthermore, Bi2O(OH)2SO4 has a small solubility product value of 1.8 3 10231 29, meaning a good stability in an aqueous media. The pH value of supernatant is 1–2 after preparation, indicating that...
在可见光照射下,分别以纯的Bi2O3、ZnO 和Bi2O3-ZnO为光催化剂,通过降解染料亚甲基蓝(MB)和苯酚进行光催化性能研究.%One-dimensional Bi2O3-ZnO composite materials have been successfully synthesized by solvothermal method using Bi2O3 nanorods as precursors.XRD pattern shows that the as-prepared ...
3. The XRD pattern showeffect of BaCO3—2.5CuO (BC) and 0.15CuO—0.85MoO3 (CM) fluxes on the thermal shrinkage and phase crystalline of T-BZN are shown in FIGS. 4 and 7, respectively. FIG. 4 shows that the addition of BC flux will affect the densification process of T-BZN ceramics...
