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. [Keywords: Ferroelectrics, Calcium titanate, Hydrothermal, Porous materials]
