In order to control the grain size of semiconductive SrTiO3 ceramics, the effects of calcination condition and Sr/Ti ratio on the sintering process of this compound has been investigated. The particle size of calcined powder increases substantially with increase of calcining temperature in the Sr/Ti ratio ranging from 0.993 to 0.999, which suggests that the Sr/Ti ratio plays an important roll in particle size growth. It has been confirmed that the grain size of sintered body is controlled by particle size of calcined powder.
