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.Entities:
