This article presents the results of BaTiO3 formation from K2Ti6O13 nano-wires under hydrothermal conditions. The main focus was on determination of the conditions for the formation of BaTiO3 with a high tetragonality. We proved that the growth of BaTiO3 particles occurred via-dissolution-precipitation mechanism. For this reasons the morphology of initial titanate precursor was not preserved. By means of Rietveld analysis, Raman spectroscopy and DSC measurements it was confirmed that higher temperatures of 200-240°C, lower concentrations of precursors and NaOH enable the formation of BaTiO3 with higher tetragonality.
