Microstructure and Electromagnetic Properties of Ni

4 Conclusions We have investigated the impact of heat treatment during the production of cubic ferrite Ni 0 25 Zn 0 25 Co 0 5 Fe 2 O 4 on its microwave electromagnetic properties By varying the top temperature values during prefiring 750 C 1000 C and sintering 1200 C 1250 C single-phase spinel ferrite with similar crystal structure and different microstructure was obtained...

Bi3 doping

In this work we synthesized Bi 3 -substituted NiCuZn ferrite to adjust the microstructure magnetic and dielectric properties at low sintering temperatures It is shown that Bi 3 substitution not only enhances grain growth and compactness of NiCuZn ferrite at low sintering temperatures but also effectively tailors the permeability permittivity and loss factor...
