摘要

The phase pure Copper Ferrite, Zinc Ferrite, and Nickel Ferrite were prepared from oxides of Ni, Cu, Zn, and Fe using traditional ceramic method. X-ray diffraction data were collected and the formation of the spinal phase structure was found. The lattice parameter was found to be 8.441 <span style="white-space:nowrap;">&#197;</span> for Zn<span style="white-space:normal;">Fe</span><sub style="white-space:normal;">2</sub><span style="white-space:normal;">O</span><sub style="white-space:normal;">4</sub>, 8.35 <span style="white-space:nowrap;">&#197;</span> for Ni<span style="white-space:normal;">Fe</span><sub style="white-space:normal;">2</sub><span style="white-space:normal;">O</span><sub style="white-space:normal;">4</sub>, and 8.349 <span style="white-space:nowrap;">&#197;</span> for Cu<span style="white-space:normal;">Fe</span><sub style="white-space:normal;">2</sub><span style="white-space:normal;">O</span><sub style="white-space:normal;">4</sub>. The Ni_0.4Zn_0.6Fe₂O₄ ferrite was sintered at three different temperatures: namely 1100<span style="white-space:nowrap;">&#176;</span>C, 1200<span style="white-space:nowrap;">&#176;</span>C, and 1300<span style="white-space:nowrap;">&#176;</span>C and similar temperature control was applied to Cu_0.2Ni_0.2Zn_0.4<span style="white-space:normal;">Fe</span><sub style="white-space:normal;">2</sub><span style="white-space:normal;">O</span><sub style="white-space:normal;">4</sub> ferrite group.
