Grain-Size Effects on Diffuse Phase Transitions of Batio3 Ceramics Obtained by Alkoxide Precursors

MRS Online Proceedings Library volume 346, pages309–314(1994)Cite this article

Abstract

Barium titanate ceramics have been obtained by sol-gel methods. The dielectric investigations of these materials revealed the existence of diffuse ferroelectric transitions. By using a phenomenological model, we could demonstrate the existence of a simple relationship between the diffuse character of the transition and the sample grain-size. This effect has been attributed to interactions between charged defects on the grain surfaces and the spontaneous polarization of the material.
