Abstract
Precipitation of TiO2 occurs during the sintering of SrTiO3 with V2O5 added as a liquid‐phase sintering agent. Satisfactory densification can be obtained at 1250°C when using a high content of V2O5 during sintering. However, a microstructure of fine grains and large pores results along with the precipitation of TiO2. The precipitation of TiO2 can be repressed by the addition of excess SrO. A well‐sintered microstructure with superior densification can thus be obtained at 125O°C from specimens sintered with a low content of V2O5 and an appropriate amount of excess SrO.Keywords
