| Abstract |
Several titanate powders (Al2TiO5, SrTiO3, etc.) were synthesized by an ethylene glycol
solution route. Titanium isopropoxide and nitrate salts were dissolved in stoichiometric proportions
in liquid-type ethylene glycol without any precipitation. The parent precursor sols were dried to
porous gels, and then the gels were calcined and crystallized. All synthesized titanate powders had
stable crystallization behavior at low temperature and high specific surface area after a simple
ball-milling process. A three-component PZT (Pb(Zr0.52·Ti0.48)O3) powder was also synthesized
successfully by the ethylene glycol method. In this study, the characteristics of the multi-component
titanate powders by the ethylene glycol method are examined. |
