perfect. In X-ray crystallography various techniques have been employed to provide some measure of this order. One such technique known as the Hinckley index is based upon the ratio of intensity of peaks in theXRDpattern. Kaolinites with many defects in the stacking are known as disordered ...
The results revealed a very slight increase in the d‐spacing of kaolinite XRD peaks. SEM images showed hexagonal platy sheets of kaolinite crystals that are indistinguishable in KPAn nanocomposites images, especially on using a high amount of polyaniline (PANI). The increase in the percentage of...
XRD:X-ray powder diffraction data were collected in a standard laboratory diffractometer Rigaku-Dairix with CuKα radiation and Bragg–Brentano geometry. The diffractometer was set in step-scan mode with steps of 0.01° and with a counting time of 5 s. The powder samples were prepared by back...
The phase structures of as-prepared composites were further explored by XRD. As shown in the XRD patterns (Fig. 3 (a)), the peak at 12.28° was indexed as the (001) crystal plane of kaolinite (JCPDS No.14–0164). Additionally, the diffraction peaks at 24.82°, 38.34° and 62.26° co...
However, these peaks were absent after being adsorbed on kaolinite surfaces, suggesting that the removal of AT from solution was via sorption instead of precipitation. In addition, the (001) peak of kaolinite did not change at all (Figure 8), indicating that AT sorption sites were on the ...
Also, XRD pattern of synthesizes zeolites are shown in Fig. 1d. Two characteristic peaks at 2Ɵ of 7–10 and 23–25° (JCPDS Card No. 01–079–2401) confirm the formation of H-ZSM536. Scherrer equation was used to calculate the crystal size from the high-intensity peaks at 2Ɵ ...
Kaolinite and dickite XRD patterns from 70 to7382uobtained using CuKaradiation (Rusinova et al. 1974).Diagnostic peaks are indicated for kaolinite (K) and dickite (D).Patterns are for (a) dickite-1 (.5mm), (b) dickite-2 (,3mm)before experiment, (c) dickite-2 (,3mm) after ...
The peaks intensity and resolution of the kaolinite decrease according to the alkalinity of the solution by the results of the IR testing. And the peak intensity increases in the 60 to 70range due to dehydration reaction observed by TG-DTA. Such phenomena was the result of increase of ...
The XRD spectra of the BM, kaolinite deposits, and synthesized materials are shown in Fig.1. The various visible peaks on the spectra of all the synthesized materials demonstrate the presence of crystalline minerals and inorganic materials. The XRD patterns of raw materials, such as kaolinite clay...
