The existing forms of iron in rutile and its influence on the physical properties of the mineral

  • Zhang Huifen

  1. (1)

    The extent of exsolution depends mainly on the content of Fe in rutile. 0.88% Fe2O3 is regarded as the lower limit of Fe content for the occurrence of exsolution in ferro — minerals. With increasing Fe content, exsolution will tend to become more and more obvious.

  2. (2)

    Iron in rutile exists mainly in the form of Fe3+, which is isomorphously substituted for Ti4+, i.e., an exsolution mineral — titano — hematite.

  3. (3)

    The iron content of rutile is a factor leading to the differences in physical properties for rutile samples.
