Abstract Gallium bearing ferrites with different gallium content were synthesized by oxidation of ferrous and gallium ions under alkaline condition and room temperature. The samples were subjected to IR,XRD,Mossbauer spectral analysis and magnetization characterization. The results indicated that the green-rust intermediate phase would be produced during the procedure of Ga-Fe3O4 formation,and the green-rust intermediate phase was converted to ferrites with spinel structure during the drying under hot-N2 atmosphere. With the introduction of gallium into the spinel structure,the interplanar crystal spacing of the spinel structure decreased,as indicated from XRD spectra,and the lattice vibration of MT—O—MO moved to the high-frequency resulting from IR spectra. A small amount gallium introduction entered the tetrahedral sites preferentially rather than the octahedral sites,and increasing gallium introduction would enhance the occupation of octahedral sites. Furthermore,a small content of gallium in the initial solution could prevent the formation of non-magnetic Fe2O3.
