Surface| Summary: | Parameters of mechanochemical synthesis of barium titanate particles with size of 12-22.4 nm from barium titanyl oxalate were determined.  Using X-ray diffraction, IR-spectroscopy (DRIFT), Raman spectroscopy, differential scanning calorimetry and spectroscopy of dielectrics it was shown that the particles contain the cubic and tetragonal modifications of the crystal lattice. The paraelectric- to- ferroelectric phase transition occurs at 133 oC. The particles prepared  by mechanochemical synthesis and thermal decomposition of barium titanyl oxalate or mixture of barium and titane oxides contain the same impurity composition.   |
