Paper Title:
Preparation of Cobalt and Copper Superfine Composite Oxides and Magnetic Property
  Abstract

A series of Co–Cu composite oxides with different susceptibility were prepared by a microemulsion method. XRD, TEM, EDS,FT-IR spectra , TG-DSC and magnetic balance were used to characterize the structure , thermostability and susceptibility of the composite oxides. The results indicate that sintering temperature has an apparent effect on the formation of the spinel structure, As the composite powders are annealed at 500 °C,the Co–Cu composite oxide was CuO 、CoO、 Cu2CoO3 and Co3O4 , but the susceptibilities of Co-Cu composite were found decreased with the annealing, and particle sizes of the composite oxides were increased in the beginning, and then became lower with the annealing .The element Co is found when the calcinations temperature is lower than 300°C.particle sizes of the composite oxides were increased at beginning, then reduced, and increased when over 500°C
