本文研究了Mn_3O_4和Fe_2O_3按1：3的摩尔比混合，采用四种不同的烧成循环，通过固相反应生成锰铁氧体。通过X射线衍射、光学显微镜、质量分析和差热分析等手段对固相反应进行了观察。从磁滞跳变和磁导率测量确定磁参数。详细研究了锰氧化物和铁氧化物的固溶体的形成，其先于铁素体的形成。用光学显微镜和X射线衍射研究了高温缓慢冷却的铁氧体的表面氧化和出溶。
An investigation has been made of the formation of manganese ferrite by solid-state reaction from mixtures of Mn3O4 and Fe2O3 in a 1 : 3 mole ratio, employing four different firing cycles. The solid-state reaction was observed by means of X-ray diffraction, optical microscopy, mass analysis, and differential thermal analysis. Magnetic parameters were determined from hysteresis hop and permeability measurements. The formation of solid solutions of manganese oxide and ferric oxide, which precedes the ferrite formation, was studied in detail. Surface oxidation and exsolution in ferrite bodies cooled slowly from high temperatures were studied by optical microscopy and X-ray diffraction.
