Sažetak

Methods for the crystal structure determination from powder diffraction data are reviewed with special emphasis on the application to technical ceramics. Experimental techniques using other than laboratory X-ray, such as synchrotron radiation, neutron and electron beams, are also described. As an illustrative example, the crystal structure determinations of compounds LaNbTiO₆, La_0.462Nb_0.614Ti_0.386O₃ and La_0.37Nb_0.889Ti_0.111O₃ in the ternary system of La₂O₃–Nb₂O₅–TiO₂ are reported.
