Abstract :
Aseries of samples was sintered from nanometric BaTiO3 powder by spark
plasma sintering (SPS). Sintered tablets were polished, sputtered by
aluminum to create electrode system and tested in DC and AC electric
fields. The results were correlated with the SPS processing parameters and are
discussed in connection with other BaTiO3 samples produced by SPS with or
without additional heat treatment. Majority of our SPS fired samples had, even
without subsequent thermal treatment, advantageous combination of high
permittivity, DC resistivity and low loss factor, seldom reported for SPS
technology. Samples were tested also in annealed state and compared with assintered
ones. Prog. Color Colorants Coat. 13 (2020), 85-92© Institute for Color
