Properties of K0.5Na0.5NbO3 – Ni0.4Zn0.6Fe2O4 composites synthesised by wet chemistry methods

KNN powders were synthesised using a modified Pechini method with citric acid as a chelating agent, while NZF powders were prepared by chemical co-precipitation. The powders were mixed in selected ratios, ball-milled, pressed into pellets and sintered in air.

The materials were characterised using X-ray diffraction, scanning electron microscopy, FT-IR spectroscopy, differential scanning calorimetry and electrical and magnetic measurements.
