The Effect of Titanium on Some Physical Properties of CuFe2O4

The mixed ferrite Cu1−xTixFe2O4 (where x = 0 to 0.7) are prepared by the ceramic method. X-ray diffraction and IR absorption spectra in the range from 200 to 1000 cm−1 are used for analysing the compositions. It is observed that samples with x ≦ 0.4 exhibit spinel phase, whereas for x > 0.4 mixed phases of spinel and zincblende may be formed. For single phase x ≦ 0.4, the theoretical lattice parameter (ath) is in good agreement with the experimental value (aexp), which is of the order of 0.833 nm. The presence of Fe2+ ion in the A-site for all samples is realized and the entrance of Ti4+ ion into the A-site just starts at x = 0.4. Some physical properties such as density, porosity, shrinkage, and conductivity at room temperature are studied.
