2.2.4 X-ray Diffraction (XRD)
XRD was conducted at ambient temperature with
X’pert PRO X-ray diffractometer (PANalytical,
Netherlands) having an X-ray tube producing
monochromatic CuK radiation. Powdered samples were
mounted onto sample stage to record the crystallinity
index. Sample stage was mounted on horizontal axis and
the diffracted beam optics and the detector were mounted
on 2 axis. The scanning rate was 0.5°/min at 2 = 5° -
35° under the acceleration voltage of 30 KV and 20 mA.
