of Nonferrous Metals, 2004, 14(11): 1901-1905. [17]John A M, Jose R, Koshy J. Synthesis and rapid densification of nanoparticles of barium praseodymium hafnium oxide: a new complex perovskite[J]. J Nanoparticle..., respectively. The experimental results indicate that the Ba(Ce0.8Zr0.2)0.9Y0.1O3-δ micro-powders with single rhombic perovskite structure can be directly synthesized through controlling the ratio......
oxides by sintering in airs using a conventional mixed oxide process. Thermogravimetry-differential analyzer (TG-DTA) analysis shows that the fired temperature of the Ba(Mg1/3, Nb2/3)O3 is above 1627.2 K. From the study of X-ray diffraction (XRD) patterns, it is founded that the amount of the perovskite phase increases with the increasing amount of La2O3. Furthermore, by the X-ray photoelectron......
Total conductivity,oxygen permeability and stability of perovskite-type oxide BaCo0.7Fe0.2Nb0.1O3-δZHANG Yuwen,LIU Yong,Wang Chenglei,YANG Zhibin,DING Weizhong,and LU Xionggang Shanghai Key... permeability and stability of pure perovskite-type oxide BaCo0.7Fe0.2Nb0.1O3-δ (BCFNO) in real operating conditions were investigated. Its total conductivity was measured to be 3.6 S·cm-1 at 600°C. Though......
