摘要: The structural aspects of a soft synthetic route employed to obtain fine crystallite $\mathrm{Pb}{\mathrm{Zr}}_{1\ensuremath{-}x}{\mathrm{Ti}}_{x}{\mathrm{O}}_{3}$ $(x=0,0.5,1)$ powders are revealed by total x-ray diffraction and atomic pair distribution function analysis. It is found that the atomic-scale structure intermediate, highly disordered phase passes through resembles but not exactly targeted, perovskite-type structure. suggested future synthesis efforts directed toward closing observed ``structure gap'' as much possible.
