When compacts of BaTiO 3 powder containing small amounts of uncombined TiO 2 were sintered, marked differences in microstructural evolution were observed under varying heating rates. In fast heating, the liquid formed during heating agglomerated at the center of the specimen and resulted in an inhomogeneous microstructure. A slower heating rate resulted in a homogeneous microstructure.
