Abstract

Factor analysis was applied to X-ray diffraction patterns of the precursor of $BaTiO_3$. For that purpose, the precursor was synthesized in water solvent system using $Ba(NO_3)_2$ and $TiO(NO_3)_2$ as the starting materials and calcined at various temperatures. The samples obtained from the various calcined temperatures were analyzed by the X-ray diffractometer. Factor analysis was applied to the intensity data of the X-ray diffraction patterns. As the results, three factors were found and they were found to be $BaCO_3$, $BaTiO_3$ and $Ba_2TiO_4$. The relative concentrations of the three components were estimated during calcination.
