摘要
The nanosized mixture powders of ferric oxide and nickel oxide prepared by the coprecipitation in a stoichiometric ratio to form NiFe2O4 Were subjected to shock wave treatment. The nanosized nickel ferrites with different particle sizes were synthesized by means of varying, initial packing density of the mixture. Compared with nickel ferrite prepared by conventional calcination, the magnetization of ones by shock wave treatment increases significantly. It is believed that shock wave treatment is a novel method for the preparation of nanosized powders of composite metal oxides with particular physical properties. (C) 2001 Elsevier Science Ltd.
