摘要：

The first mechanochemical synthesis of nanosized YAl1-xFexO3 (X = 0 to 1) perovskite powders is reported. Continuous ball-milling of the yttria, aluminum hydroxide and iron oxide powders over 24 h led to the formation of nanocrystals with a size of nearly 20 nm. It has been found that the material exhibits a catalytic property for preparing carbon nanotubes. (C) 2003 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
