SPECIAL FEATURES OF THE FORMATION OF NEW PHASES ON HEATING BARIUM TITANATE POWDERS WITH ZIRCONIUM DIOXIDE MICRO- OR NANOPOWDERS

摘要

To modify barium titanate to displace the phase transition from 125℃ toward lower temperatures, various elements replacing barium or titanium cations, in particular, zirconium atoms are used [1, 2]. The present work is aimed at investigation of the influence of the modification temperature of barium titanate powders with zirconium dioxide micro- or nanopowder in the interval 800–1200℃ on the phase composition and diffusion reflection spectra of the compounds obtained.
