Abstract
Enhancement of consolidation behavior in SPS process was verified by examining the solid solution reaction between barium titanate (BTO) and strontium titanate (STO) powders, compared with that in the conventional heating method. It was found that the solid solution reaction between BTO and STO occurred at about 200°C lower temperature in SPS process than that in the conventional process. The increase of heating rate accelerated the formation of BTO-STO solid solution in the SPS process, indicating that the pulsed high current effect (that is, SPS effect) generates at higher heating rate.
