lines connecting the two meltings or the two transformation points of Ce and La. Without further information, the ideal solution model was used to describe the liquid phase and the solid solution phases... CeO1.5 and LaO1.5, four continuous solid solution phases named as A, C, H and X should be formed in the CeO1.5-LaO1.5 system. No experimental phase diagram data have been reported for the CeO1.5-LaO1.5......

Performance of La1-xSrxCr1-yMnyO3-δ anode materials for intermediate temperature solid oxide fuel cell CHEN Xiu-hua(陈秀华)1, MA Wen-hui(马文会)2, 3, YANG Bin(杨 斌)2, 3, DAI Yong-nian(戴永年)2, 3 1... reduction(TPR) techniques. XRD patterns indicate that perovskite phase created after the precursor was sintered at 1 000 ℃ for 5 h, and single perovskite-type oxides formed after the precursor were......
was preserved for ready-use; the concentrations of the manganese and chloride in solid phase were analyzed, and the XRD (X'Pert-Pro, the harrow material is copper) analysis was carried out after the solid... to separate solid and liquid phase. The concentration of manganese in liquid phase was analyzed in order to calculate the solubility of Mn2(OH)3Cl in water. This step was repeated several times to make sure......
, China) Abstract:Strontium doped lanthanum manganite (LSM) powders were synthesized by three different routes: azeotropic distillation, sol-gel and solid state reaction respectively. The LSM samples, made by azeotropic distillation and sol-gel methods were prepared by firing at 1000 ℃ for 6 h, and the LSM sample, made by solid state reaction method was produced by sintering at 1400 ℃ for 18 h......
Preparation of Solid Solutions [Li3xLa0.67-xYyTi1-2yNbyO3] and Its Lithium-ion Conductivity 王文继1,陈睿婷1,李荣华1 (1.Department of Chemistry,Fuzhou University,Fuzhou 350002, China) Abstract:Perovskite-type lithium fast ion conductors of Li3xLa0.67-xYyTi1-2yNbyO3 system were prepared by solid state reaction. X-Ray powder diffraction shows that a single-phase perovskite solid solution with orthorhombic......
at these temperatures. In fact, the Co3Ta phase is reported to form a continuous ternary solid solution extending from the Laves_C36_Co3Ta to the Laves_C36_Co2Ti phase [13]. The Co3Ti phase also has... type Co3Ti phase. 3) Isothermal sections in the Co-rich region of the Co-Ti-Ta system at 1 000, 1 100 and 1 200 °C are constructed based on the measurements in this work. The determined solid......
and silicate. The individual fired pellets are hardened by solid phase diffusion and the racemose sinter are consolidated by both solid phase diffusion and liquid phase bonding, the latter is 30% in sinter. Key words: chromite concentrate; pellet sintering process; wet ball milling; solid diffusion consolidation; liquid phase bonding 铬铁矿是生产铬铁合金的重要原料.但是,我国铬矿资源贫乏,保有储量仅占世界储量的0.15%,95% 铬铁矿依靠进口,进口量达302万......
