Magnetite - an overview | ScienceDirect Topics

Magnetite is one of the end members of the ulvospinel-magnetite solid solution series (Fig. 3.3) and is the most common magnetic mineral on Earth.Magnetite is a cubic mineral with inverse spinel structure. The disordering (Curie) temperature varies more or less linearly with Ti content from -150°C for ulvospinel to 580°C for magnetite (Fig. 3.4 a).

Magnetite - an overview | ScienceDirect Topics

Magnetite, ideal formula Fe 3 O 4, is an intriguing mineral, and not only because it is magnetic.The formula could be written as Fe 2+ Fe 3+ 2O 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.
