The model shows that, for non-spherical nano-crystallite, its XRD peak broadening becomes anisotropic and orientation (h k l) dependent. In such a case, the crystallite size must be described by multi-dimensional lengths, possible with a polar orientation. Experiments on -Ni(OH)2, -TiO2 and...
However, when x=0, a second phase of Ba5Nb4O15 (JCPDS card no. 14-0028) emerges in the BMN ceramic. The (420) diffraction peak at a high angle shifts to a lower angle with increasing Zr4+ content, and the cell constant of the BMZN solid solution increases. The splitting of ...
