(Color online) Selected Bragg reflections of NBT from room temperature to 600 °C.
(Color online) (a) Rietveld refinement of the pattern measured at 250 °C showing the observed pattern (x) and the calculated fit (—). Detail of the 110 and 200 peaks is shown in part (b) as well as the ½(311) and 111 peaks in part (c). Reflection markers for the Cc and Pm m phases are shown as vertical lines with the difference pattern below the diffraction pattern.
Refined phase proportions and criteria of fit parameters for all Rietveld refinements.
