MgFe2TiO4

MgFe2TiO4 is a mineral belonging to the spinel group. It is a type of ferrotitanomagnetite, a naturally occurring oxide mineral composed of magnesium, iron, and titanium. The chemical composition of MgFe2TiO4 indicates a distribution of cations in an octahedral type of crystal structure.

Mineral Properties

MgFe2TiO4 has a distinctive chemical composition and crystal structure. It is typically found in metamorphic and igneous rocks, often associated with other spinel group minerals. The mineral exhibits a range of properties, including optical, electrical, and magnetic behaviors. Studies on MgFe2TiO4 have shown that it exhibits magnetization under alternating current or some specific conditions, mainly attributed to the presence of defect sites in the crystal structure.

Geological Occurrence

MgFe2TiO4 is generally found in areas of continental rifting and collisional tectonics. Various geological environments can lead to its formation, such as low-pressure and high-temperature conditions near felsic intrusive and volcanic rocks. Secondary weathering processes often contribute to the formation of weathered concentrates in soil and drainage areas.

Thermal Properties

MgFe2TiO4 has complex thermal properties. The spinel structure offers flexibility in accommodating cations with a variety of sizes and charges, including substitution and disorder components. These factors interact with specific operating conditions to influence a range of physical and thermodynamic properties.

Composition and Modification

Chemical modification of MgFe2TiO4 involves potential doping with other cations. A range of doping can influence or intentionally cause desirable properties. Additional considerations often revolve around distortion or alteration by chemical incorporation, like substitution by other compositions, often applied in multi-component samples. These structural and chemical variations can demonstrate quasi-linear changes.
