Structural Observations, Density and Porosity Studies of Cu Substituted Ni-Zn Ferrite through Standard Ceramic Technique

Abstract

Polycrystalline NiCuZn ferrites prepared by solid state reaction method with various concentrations of copper generalized as Ni 0.7-x Cu x Zn 0.3 Fe 2 O 4 with the x varying from 0 to 0.50 in steps of 0.05 variations. In this paper we present the structural, density and porosity. The powders of the samples were used to characterize the x-ray diffraction. The XRD patterns of the samples provide the evidence of the single cubic crystal symmetry phase. The microstructure of the NiCuZn ferrite average grain size is recorded by SEM. The NiCuZn ferrite system having low cost and low firing metals for preparing the multi layer ferrite chip inductors and higher densification than the Mn-Zn ferrite.

Correlation among the structural, electric and magnetic properties of Al3+ substituted Ni–Zn–Co ferrites

“…29,30 Porosities, P (%), of the x ¼ 0 À x ¼ 0.12 samples can explain through the intragranular porosity (P intra ) and intergranular porosity (P inter ). 31 During sintering, the thermal energy causes a force that pushes the grain boundaries to grow over pores. Thus the pore volume decreases and densies the material.…”

“…24 Sintering temperature (1200 C) for the prepared ferrites remains the same throughout the studies; hence, intragranular porosities signicantly have no effects on the compositions. 29,31 During sintering inside the ferrites, intergranular porosities occur because of irregular particles. 1,28 Besides, intergranular pores can change with the grain boundaries related to the grain growth (Table 2), 1 demanding that the pores move together and merge, and a different transport mechanism indicates.…”
