Abstract This work involved the in situ synthesis, by the Pechini method, of powders of the magnetoelectric composite Sr0.61Ba0.39Nb2O6/NiFe2O4 (SBN61/NFO), in a 50/50 ratio, to obtain sintered samples with control of abnormal grain growth of the SBN61 phase. The SBN61/NFO samples were characterized by thermogravimetric analysis, X-ray diffraction, and scanning and transmission electron microscopy. The phases in the synthesized samples were quantified by the Rietveld refinement method and the result revealed that the SBN61/NFO composite contained fewer spurious phases than the SBN61 phase alone. After sintering, the SBN61/NFO composite showed a relative density of 98.6%, excellent dispersion of the NFO and SBN61 phases, a low degree of percolation of the NFO phase, and microstructure without abnormal grain growth of the SBN61 phase.
