Modification of composite ceramics properties via different preparation techniques

Modifying the proportion of the base composition by substituting with suitable dopents and improving the preparation conditions is expected to change the performance of composites. In the present study, 0.5(Ni0.5Zn0.5Fe2O4)/0.5(BaTiO3) composite was prepared by, the conventional ceramic technique and the citrate method. Ceramic particles, when prepared via different routes, would demonstrate different properties, even with the same starting compositions. With the help of X-ray diffraction, scanning electron microscope (SEM), magnetic properties, and electric properties of the composites have been compared. A critical comparison of those methods is needed to make the best choice for given boundary conditions of targeted eventual material properties, raw materials, investment, processing and waste disposal costs.

► NZF/BT nanocomposite is successfully produced by citrate and ceramic techniques.
► XRD found that, particle size and lattice constant of citrate are smaller than ceramic technique.
► Excellent magnetic and dielectric properties in a wide range of frequency.
► Citrate method offer preparation at lower temperatures.
► Citrate method is less cumbersome, more versatile, and cost effective to obtain nano composites.
