High-energy X-ray diffraction measurements were performed to analyze KNbO nanocrystals. We used KNbO nanocrystals with cubic shape. Moreover, these nanocrystals have cubic structure owing to their small crystal size. Therefore, these nanocrystals are ideal for applying the Scherrer's equation. Crystal-growth mechanism was considered with the crystal size obtained by the Scherrer's equation. It was found the growth mechanism of KNbO by comparing the crystal size and average structure obtained by Rietveld analysis and coherent size obtained by atomic pair-distribution function method.
