In the temperature range of 450-1000℃, the conductivity is 10~(-3)-10~(-2) S·cm~(-1),the activation energy in air is 0.49 eV, measured by impedance spectroscopy technology. The hydrogen sensors for measureing the hydrogen activity in molten Al alloy is manufactured, using BaCe_(0.95)Y_(0.05)O_(3-α) as solid electrolyte, metal hydride as reference electrode and Mo wire as lead wire. The results showed that the sensor has a high sensitivity and a good stability within the range of experiment temperature.(Correspondent: WANG Changzhen, professor, Faculty of Metallurgical Physical Chemistry, Northeastern University, Shenyang 110006) Key words:  sensor      BaCeO_3      solid electrolyte      activity      hydrogen      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1995/V31/I19/305 1IwaharaH,EsakaT,UchidaH．MaedaN．SolidStateIonics,1981;3-4:3592IwaharaH,UchidaH,KondoK,OgakiK．JElectrochemSoc,1988;135:5293IwaharaH,UchidaH,NaganoT,KoideK．DenkiKagaku,1989;57:9924MitsusiA,MiyamaM,YanagidaH．SolidStateIonics,1987,22:2135HibinoT,MizutaniK,YajiimaT．IwaharaH,SolidStateIonics,1992;57:3036IwaharaH．SolidStateIonics,1988;28-30:5737IwaharaH．ProceedingoftheInternationalSeminarSolidStateIonicsDevices,Singapore,1988:2898RobertCT．SolidstateIonics,1991;46:1119YajimaT,IwaharaH．SolidStateIonics,1991;47:11710ScherbanT,LeeWK,NowickAS．SolidStateIonics,1988;28-30:585 [1] LI Qian, SUN Xuan, LUO Qun, LIU Bin, WU Chengzhang, PAN Fusheng.
