A Study of Lattice Parameter of Ni – Zn Ferrite Modified by Addition of Silicon

The purpose of this study is to provide precise quantitative data for the lattice parameter as a function of silicon concentration, which can be used as a means of determining composition of samples. The results of lattice parameter measurements on the series 65.0 35.0 Fe2 O4 Ni Zn Six −x ferrite over the range 0 ≤ x ≤ 5.0 are reported. The lattice constants were calculated by two ways: first, as average and second, in terms of diffractometer extrapolation function. The single phase spinel structure of the sample was confirmed by X – ray diffraction technique. We found that the lattice constant decreases as x increasing. In addition, we calculated the cation – cation distance dc-c in the tetrahedral and octahedral sites.
