Abstract

The effect of the sample particle size on the crystal structure and the Curie temperature of BaTiO3 powder has been investigated in the particle size range 0.1 to 1.0 μm. The transformation from tetragonal to cubic symmetry occurs at a critical particle size of 0.12 μm at room temperature, and the Curie temperature drops below room temperature at the critical particle size.
