Continuous Hydrothermal Preparation of Partially Substituted Perovskite Oxide Nanoparticles
Using a supercritical flow system, in which supercritical water was utilized as reaction medium, nanoparticles of partially substituted perovskite oxide (Ca 0.8 Sr 0.2 Ti 0.9 Fe 0.1 O 3-α ) were rapidly formed within a 10s reaction time. The average particle size is 20 nm, and BET specific surface area is 70.6 m 2 /g.
