Performance of NiCu ferrite fine particles and ceramics synthesized using egg white

NiCu ferrite fine particles were synthesized with Ni, Cu, Fe nitrates - egg white and nitrates - citrate acid. And Ni(1-x)CuxFe2O4(x=0,0.2,0.4,0.6) ferrite ceramics with the same raw materials were prepared by solid state reaction. The results of X-ray diffraction showed that the main phase, NiCu ferrite with fine particles were obtained from the nitrates-egg white or nitrates-citrate acid mixture calcined at 400°C for 3 hs. Vibrating Sample Magnetometer (VSM) measurements indicated the NiCu material with fine particles were typical soft magnetic materials. Combined results of magnetization curves, saturation magnetization (Ms), residual magnetization (Mr), coercitive force (Hc), it has been found that the NiCu ferrite material synthesized from nitrates - egg white has better magnetic performance than that from nitrates -citrate acid. Cu doping can increase the Ni-ferrite's permeability. The Ni0.6Cu0.4Fe2O4 (x=0.4) fine particle and bulk ceramic have excellent magnetics properties.
