| Abstract: | Ultrafine BaTiO 3 powders were prepared by sol gel methods. The crystalline structure of the powders prepared by different process was studied by XRD. Crystal size was calculated according to the Scherrer formula. The size effect on BaTiO 3 Curie phase transition was observed by DSC experiments. The relation between the grain size and firing temperature was analysed. The morphology of the powders was observed by SEM. |
