Abstract
All magnetites are oxidized topotactically with formation of solid solution at temperatures below 400 degrees C. The oxidation of hematite-free magnetites proceeds to gammaFe(2)O(3), whereas in the presence of hematite epitaxial growth of alphaFe(2)O(3) takes place, with excess iron ions being returned to the solid solution. A method for synthesizing maghemite from natural magnetites is indicated.
摘要
所有磁铁矿在低于 400°C 的温度下都通过同构氧化形成固溶体。无赤铁矿磁铁矿的氧化产物为 γ-Fe2O3，而在赤铁矿存在的情况下则发生 α-Fe2O3 的外延生长，过量的铁离子返回固溶体。文中还介绍了一种从天然磁铁矿合成磁赤铁矿的方法。
