The mean diameters (µm) of MK and FA were 16.26 and 51.06, respectively. The mineral phases were identified, see Figure 1b, using XRD measurement (Miniflex, Rigaku). Shear stress and apparent ...

X-ray diffraction patterns of both, instead of showing the sharp rings or spots associated with crystal structures, show diffuse bands indicating that the type of order existing in them is limited ...
