2004:07 The Stability of Magnetite and its Significance as a Passivating Film in the Repository Environment (pdf, 915 kB)
to corrode. Earlier studies have indicated that a passivating film of magnetite (Fe3O4) is formed on the iron. If this is valid also in high chloride and sulphide concentrations is though not shown. ... project was to investigate, by a literature study, if magnetite could be formed as a passivating film on iron in the expected repository conditions. The possibility to form other types of passivating films...
