The high-energy X-ray diffraction experiments of KNbO nanocrystals were carried out. Although Scherrer's equation may be used in estimating the particle diameters, in practical use there are various restrictions. In this study, we used KNbO nanocrystals synthesized by a solvothermal method with a cubic shape. The crystal structure were a cubic structure because of the small particle size, it can be said that the KNbO sample is an ideal to apply the Scherrer's equation. The crystal growth proceeds with the reaction time was investigated the kinetics of crystal growth. The short-range order structure was also observed, which was directly determined in the real space from the atomic pair-distribution distribution function method. It was found that the initial growth of KNbO nano crystal was suppressed because of lattice defects.
