抄録

Manganese ferrites were quickly prepared from manganese oxide and iron oxide powders by a microwave discharge generated between two pieces of carbon felt (MD/CF) with various powers in air atmosphere, and were characterized especially by X-ray diffractometry and Mössbauer spectroscopy. MnFe₂O₄ was produced within at least 40 s by MD/CF with more than 200 W microwave power in air atmosphere. With the increase of the applied microwave power, FeO powders were produced in addition to distorted MnFe₂O₄ by using MnO and Fe₂O₃ powders as starting mixture. Improved yield for MnFe₂O₄ were obtained by post annealing for 1 hour or by using the raw mixed materials of MnO, MnO₂ and Fe₂O₃.
