Magnetite - an overview | ScienceDirect Topics

Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral not only because it is magnetic.The formula could be written as Fe 2 + Fe 3 + 2 O 4, which more precisely designates one of its peculiarities.It contains both ferrous (Fe 2 +) and ferric (Fe 3 +) ions, implying synthesis, growth, and stability within an environment where oxidized and reduced states of iron are present and maintained.
