2015-11-18  Perovskite La 0.6 Sr 0.4 CoO 3-δ was ball milled (BM LSC 1000) at various time periods and the effect of ball milling on structural and electrochemical characteristics were investigated. As the ball milling time increased, the particle size decreased and the surface area increased. Upon prolonged ball milling up to 48 hours, however, the particle size and surface area got stabilized.
