Hollow Glass Microspheres Coated with La_0.6Sr_0.4MnO₃ and its Microwave Absorption Property

Abstract:

La_0.6Sr_0.4MnO₃ and hollow glass microspheres with different weight ratio have been prepared by sol-gel method. The structure, morphology and microwave absorption properties have been investigated. The results shown that the ratio of La_0.6Sr_0.4MnO₃ to hollow glass microspheres has great influence on reflection loss. The optimal absorption property can be obtained when the ratio is 6:1, which is attributed to the proper magnetic loss of La_0.6Sr_0.4MnO₃ coating layers.
