【 摘 要 】

References(19)Submicron particles comprising nanocrystallites of Gd0.1Ce0.9O1.95 (GDC), NiO–Gd0.1Ce0.9O1.95 (NiO–GDC), and La0.8Sr0.2CoO3 (LSC) were synthesized using ultrasonic spray pyrolysis in a reactor at 1,273 K for 13 s. Nitrates of the component metals were used as precursors and dissolved in pure water in stoichiometric amounts of GDC, NiO–GDC, and LSC. GDC and NiO–GDC were spherical, whereas LSC were nonspherical. The crystalline nature of GDC improved on increasing the reactor temperature from 773 to 1,273 K during the reaction time of 13 s. The average sizes of NiO–GDC and LSC crystallites prepared using the solution concentration of 0.2 mol L−1 were bigger than those prepared using 0.02 mol L−1 solutions.
