Aiming toward an optimization of dual phase oxygen transport membrane materials for separation applications, ceramic composites consisting a Ce 1− x Gd O 2− δ (0 < 0.2) fluorite phase, 0.9 0.1 Fe 0.8 Co 0.2 3 perovskite 3− 4 1) spinel and CoO rock salt are developed micromechanical properties (elastic modulus hardness) : (1− )FeCo 2 (50 wt% ≤ 90 wt%) characterized via indentation testing at room temperature. The results obtained low loads indicate that the magnitude elastic moduli...
Abstract Ce 0.8 Gd 0.2 O 2− δ ‐FeCo 2 4 composites are attractive candidate materials for high‐purity oxygen generation providing robust chemical stability. Aiming future industrial applications, a feasible solid‐state reaction process with one thermal processing step was used to synthesize 50 wt% :50 FeCo and 85 :15 composites. Mechanical reliabilities of the sintered membranes were assessed based on characterized mechanical properties subcritical crack growth behavior. In general, fracture...
BaCe0.65Zr0.2Y0.15O3-δ (BCZ20Y15) has raised great interest due to its good protonic conductivity and chemical stability. However, the sintering of material is considerably challenged by refractory nature. In current work, almost fully densified single-phase BCZ20Y15 with grain sizes exceeding 10 μm was successfully fabricated at 1500 °C using calcinated powders consisting naturally separated perovskite phases 0.5 wt.% NiO. The role NiO as aid elucidated Inductively Coupled Plasma Optical...
Nanometre coating is the combination and comprehensive application of nanomaterial's surface engineering technology. It has been always regarded as a special field by foreign militaries. Ships, aircraft land equipment are facing extreme service conditions, including corrosion, wear, high temperature other effects, well resulting operation failure life expectancy decline. Nano-coating can solve above problems more effectively. increasingly used in military. Compared with technologies, thermal...
Metal supported catalysts in hydrogen production reactor has a very broad application prospect. However, the film adhesion of active coating with metal support is key problem which needed to be solved urgently. In this paper, FeCrAl alloy was chosen as metallic substrate. The effects oxidation temperature and time on morphology, crystal phase element composition surface were investigated by XRD, SEM EDAX. results show that after pre-treatment Metallic Substrate,a dense transition layer α-Al...
