【摘要】 <正> Fe₃O₄是磁铁矿石中主要含铁成分。我国很多大的铁矿是磁铁矿,例如鞍山铁矿、攀枝花铁矿和迁安铁矿。在有些自然铁矿石中含有一定量的含钾和钠的脉石。在选矿和烧结后仍进入最后的矿石球团中,对于矿石在高炉中的行为有很大的影响。所以研究钾、钠化合物对Fe₃O₄的氧化和还原行为的作用是很必要的。更多还原

【Abstract】 The effect of patossium and sodium on the oxidation and reduction of Fe3O4 is studied by means of Mossbauer spectroscopy.It is shown that the main effect of patossium and sodium seems to form patossium-bearing or sodium-bearing new compounds in the oxidation of Fe3O4 and the patossium and sodium ions get into the lattices of Fe3O4 and FexO and act as promoting reduction in the reduction.更多还原
