Maghemite in Brazilian Iron Ores: Quantification of the

For magnetite with an ideal Fe 2+ content (assuming the Fe 3 O 4 formula), the mineral phase is known as stoichiometric magnetite (χ = 0.50). As magnetite becomes oxidized, the Fe 2+ /Fe 3+ ratio decreases (χ < 0.50), with this form denoted as nonstoichiometric or …
