Simulation of the powder diffraction pattern of randomly restacked Ca2Nb3O10nanosheets

From X-ray powder diffraction pattern features, layered KCa 2 Nb 3 O 10 · n H 2 O synthesized through flocculation of delaminated Ca 2 Nb 3 O 10 nanosheets with K ions appeared to be composed of randomly stacked nanosheets. Powder pattern simulation was conducted based on the matrix method using a random stacking model. When seven sheets were used as the coherent thickness, agreement in pattern fitting between the experimental and calculated intensities was satisfactory, and information about textures and atomic positions was obtained.
