By insertion of the probe into liquid Al sample, the hydrogen concentration cell: Mo, Ca/CaH2｜H＋conductor[H]molten Al, Mo, is available to determine its hydrogen content. EMF of the probe was stable for 1.8 ks and also responded rapidly and accurately to the dehydrogenation by hexachloroethane. XRD and TG analysis of the recovered proton conductor showed that no other phase but perovskite was identified and the excess of Sr improves the stabiltiy of the proton conductor under strong reducing atmosphere. Key words： StCeO_3    proton conductor    hydrogen probe    liquid Al      基金资助:国家自然科学基金 服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 郑敏辉 陈祥 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1994/V30/I17/238 1北村照夫．铁匕钢,1989:75:3962GeeR,FrayDJ．Metall,Trans,1978;9B:4273IwaharaH,EsakaT,UchidaH,MaedaN．SolidStateIonics,1981;3//4:3594矢岛保,岩原弘育,武津典彦,大桥照男,小出邦博．轻金属,1992;263:425郑敏辉,甄秀欣,马淑云．第四届全国高技术陶瓷学术年会论文集,1992,4396甄秀欣,郑敏辉,第四届全国高技术陶瓷学术年会论文集,1992,4427ZhengM,ZhenX．SolidStateIonics,1993;59:1678ZhengM,ZhenX．MetallTransB,1993;24B:7899RansleyGE,NeufeldH．JInstMet,1948;74:59910CurtisRW,ChiottiP．JPhysChem,1963;67:1061z [1] 厉英,丁玉石,崔绍刚,王常珍. 掺杂Sc的CaZrO3的制备及电学性能[J]. 金属学报, 2012, 48(5): 575-578.
