MULTIFUNCTION IN SINGLE-SINTERED SrTiO3 CERAMICS徐庆摘 要:<正>The multifunction of SrTiO3 ceramics pre-pared by a single-sintering process is investigated. It is foundthat both the oxidizing annealing temperature and time showsingnificant influences on multifunction. The characteristicsof grain and grainboundary are analysed by means of ACimpedance......
