The sintered grain size was almost proportional to the particle size of the starting BaTiO3 powder. The sharp peak intensity at 130 degrees C and the broad peak intensity around the lower temperature were determined by the volume fraction of the grain cores and by the volume fraction of grain shells, respectively.
