摘要：
A significant improvement in electromagnetic wave absorbing performance is achieved in an Al(18)B(4)O(33)w/Co based coating through the heat treatment of Al(18)B(4)O(33)w/Co particles. The electromagnetic properties of the Al(18)B(4)O(33)w/Co Composite particles clearly increase after heat treatment. A maximal reflection loss of 78.3 dB and a high-efficiency absorption band of 4 GHz was obtained with an improved coating about 2 mm thick. Additionally, the absorption band was found to be able to cover the 7-18 GHz band by adjusting the coating thickness. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
