Abstract
Iron(II) manganese(II) ferrite Mn0.3Fe2.7O4 was synthesized by co-precipitation (with various options for the subsequent heat and mechanical treatment of the precipitate). The material was studied by powder X-ray diffraction, infrared spectroscopy, scanning electron microscopy, and magnetometry. The powder that was annealed under argon at 740°С (8.0 h) and subjected to high-energy milling (1.0 h) at the final stage of the synthesis is a promising functional filler for magnetorheological materials, owing to high shear stress (3500 Pa at 625 mT) of an oil suspension based on this powder and high oil absorption capacity, which ensures sedimentation stability of the suspension.
