نویسندگان
چکیده
The perovskite nanopowders of lanthanum strontium cobalt ferrite (LSCF) have been synthesized using the alginate mediated ion-exchange process. This perovskite-based material is a promising cathode for intermediate-temperature solid oxide fuel cells (IT-SOFCs) due to its high electrical conductivity, low polarizability, catalytic activity oxygen reduction, enhanced chemical stability at an elevated temperature in potential environment and compatibility with ceria based electrolytes. Phase pure LSCF 6428, 6455, 6482 corresponding La0.6Sr0.4Co0.2Fe0.8O3-δ, La0.6Sr0.4Co0.5Fe0.5O3-δ, La0.6Sr0.4Co0.8Fe0.2O3-δ, respectively were successfully synthesized. simultaneous thermal analysis (DSC-TGA) XRD used determine optimum calcination dried ion-exchanged beads. Single phase (6428, 6482) prepared 700 °C. TGA showed that every ton LSCF-ALG beads can potentially yield 360 kg suggesting scaling-up process manufacturing LSCF.

Preparation of gas-tight strontium-doped lanthanum cobaltate by an aqueous sol-gel process
Gas-tight dense membranes of highly Sr-doped LaCoO, (such as the composition La,,, Sr 0,7 COO, chosen in this study) are difficult to prepare using usual synthesis processes. This report presents an aqueous sol-gel route using metal acetates as precursors to achieve this goal. Hydrogen peroxide and ammonia are added to the acetates precursor solution to obtain stable sol and xerogel, as well as...

In this work, sol-gel processing was used to synthesize the fluorohydroxyapatite (nano-FHA, Ca10(PO4)6(OH)2−xFx) nanopowders. The advantages of the sol-gel method over other methods are precise control of composition, low processing temperature, and better homogeneity. Calcium nitrate tetrahydrate, phosphorous pentoxide and Tetrabuthylammon...
