X-ray diffractogram was obtained with X-ray diffractometer (X’Pert Pro MPD, Philips, Netherlands) equipped with a h–h goniometer. Samples were scanned with Cu-Ka radiation (k = 0.25 nm) in the angular range 2h = 5–45 with step intervals of 0.0128916 and a scanning rate of 0.02/min for continuous scanning (Blazek, Gilbert, & Copeland, 2011). The X-ray generator operating conditions were 40 kV and 30 mA. Diffractograms were processed using PeakFit software version 4.12 (SeaSolve Software Inc., Framingham, USA).
