heal.abstract	Ferrites of a d and an f transition element, viz. nickel and erbium ferrites, were prepared by a wet chemical method. Different ratios of iron to nickel oxides and iron to erbium oxides were used and the formation of the ferrites was studied over a temperature range of 800-1600-degrees-C. The changes in composition and structure of the ferrites, taking place as a function of temperature and initial oxide composition used, were investigated by thermal analysis, X-ray diffraction and Mossbauer spectra. It is shown that it is possible to prepare ferrites with a desired composition, since they maintain, after quenching at room temperature the composition and structure attained at the higher temperature. The ferrite composition is determined by the firing temperature and the initial oxide percentage.	en
