| Abstract |
| prism of perovskite calcium titanate via one-step surfactant free hydrothermal method.
Highly concentrated potassium hydroxide is used as a mineralizer in this procedure. Single
phase of CaTiO3 appears after treatment for 180 min during the one-step hydrothermal
conditions. The reaction yield is 97% and no impurity is observed in the final product.
The uniformly dispersed particles obtained from the hydrothermal method have hollow
micro square based prism morphology with an average size of about 2 m in length and
200 nm in diameter. The results indicate that the hydrothermal method is a suitable
procedure to prepare CaTiO3 microparticle with a desired morphology for industrial
applications. The optical properties of the prepared samples are also investigated.
