Abstract
Barium titanate ceramics having grain sizes between 0.5μm and 20μm were used in a comparative investigation of the ferro-para phase transition, by recording the temperature dependencies of the heat capacity and pyrocharge. The experimental results and the theoretical approach suggest that internal stresses are the main cause of the observed grain size effectsKeywords
