SONOCATALYSED HYDROTHERMAL PREPARATION OF LEAD TITANATE NANOPOWDERS

Nanoparticles of perovskite lead titanate, PbTiO3, were prepared in a stoichiometric proportion at a low temperature and short reaction time of only 130 C and 3.5 h. The use of ultrasonic treatment prior to hydrothermal reaction, or the so-called 'sonocatalysed hydrothermal reaction', was...
