Grain size effect of nano-BaTiO3ceramics has been studied on the basis of Ginsburg-Landau-Devonshire thermodynamic theory. In this study, ferroelectric domain of nano BaTiO3ceramic has been researched by a second-order transition model, size effects of the polarization and ferroelectric-paraelectric transition temperature have been analyzed. The results pointed out that with decreasing grain size, ferroelectric-paraelectric transition has occurred and the ferroelectric critical size is 22 nm, which is consistent with the ex...
