Sonochemical Synthesis of Cobalt Ferrite Nanoparticles

الملخص EN

Cobalt ferrite being a hard magnetic material with high coercivity and moderate magnetization has found wide-spread applications.

In this paper, we have reported the sonochemical synthesis of cobalt ferrite nanoparticles using metal acetate precursors.

The ferrite synthesis occurs in three steps (hydrolysis of acetates, oxidation of hydroxides, and in situ microcalcination of metal oxides) that are facilitated by physical and chemical effects of cavitation bubbles.

The physical and magnetic properties of the ferrite nano-particles thus synthesized have been found to be comparable with those reported in the literature using other synthesis techniques.
