Preparation and Characterization of Calcium Titanate (CaTiO3) Whiskers via Molten Salt Method

Article Preview

Abstract:

Well dispersive and single crystal calcium titanate (CaTiO3) whisker with a length of 50-100μm was synthesized by sintering the mixture of calcium chloride and titanium dioxide with improvement of adding the mineralization agent of Pb(Ac)2.3H2O. The as-prepared samples were characterized by XRD, SEM. The optimum synthesis condition and the effect of the mineralization agent were discussed respectively. In the end, the possible reaction process was given and a LS growth mechanism was proposed.
