摘要：
In order to enhance the tetragonality of BaTiO3 derived from barium titanyl oxalate (BTO), various treatments were carried out by considering the thermal decomposition mechanism of BTO in air. A multi-step heat treatment process and the addition of carbon black, as a particle growth inhibitor, were effective in increasing the tetragonality, whilst maintaining a particle size smaller than 200 nm. The synthesized BaTiO3 powder with a mean particle size of 177 urn showed a tetragonality and K-factor of 1.0064 and approximately 3, respectively. (C) 2009 Elsevier Ltd and Techna Group S.r.l.
