A two-body correlation distribution function obtained from high-energy X-ray diffraction experiments was applied to a niobium-based oxide ferroelectric (NaKLi)NbO - Ca(ZrTi)O with excellent piezoelectric properties. The average structure of (NaKLi)NbO - Ca(ZrTi)O changes with a small amount of Ta-additives. When the density and grain size of the sample were matched to determine whether the local structure changed with the change in the average structure, there was almost no difference in the local structure between 3 and 10. The difference was observed in the coherence of the nanoscale region, suggesting a difference in the ferroelectric domain size.
