• Preparation and characterization of perovskite ceramic

    Perovskite La 0.6 Sr 0.4 Co 0.8 Fe 0.2 O 3-δ (LSCF) powders have been successfully synthesized from oxide and carbonates based on the principle of gelcasting. Phase-forming temperature is very dependent on the ball-milling process during the suspension preparation. As the ball-milling time is increased, the temperature of phase formation decreases, therefore the perovskite powder obtained has
