Fabrication and Properties of BaTiO₃-CoFe₂O₄ Nanocomposites

Abstract

In this work, BaTiO₃-xCoFe₂O₄, where x = 0, 0.1, 0.2, 0.3, 0.4 and 0.5, nanocomposites were prepared by conventional mixing method and followed by normal sintering in air. The effect of processing condition on phase formation, microstructure, magnetic and electrical properties of the BaTiO₃-CoFe₂O₄ nanocomposites was investigated. The phase development and microstructural evolution of this system have been determined via X-ray diffractometer and scanning electron microscope. From the results, it concludes that phase formation, microstructure, electrical and magnetic properties of the BaTiO₃-xCoFe₂O₄ nanocomposites strongly depend on chemical composition.
