Titanomagnetite - an overview | ScienceDirect Topics
网页Titanomagnetites are common magnetic minerals in igneous and metamorphic rocks. Titanomagnetites (Fe3 −x Ti x O 4, 0 ≤ x ≤ 1) form a complete solid solution above ~ 923 K between end-members magnetite (Fe 3 O 4, x = 0) and ulvöspinel (Fe 2 TiO 4, x = 1). The compositional parameter x gives the fraction of ulvöspinel ( (1 − x)Fe 3 O 4 ...
Titanomagnetite - Wikipedia
网页Titanomagnetite is a mineral containing oxides of titanium and iron, with the formula Fe 2+ (Fe 3+,Ti) 2 O 4. It is also known as titaniferous magnetite, mogensenite, Ti-magnetite, or titanian magnetite. [1] It is part of the spinel group of minerals.

Magnetic Domain States and Critical Sizes in the Titanomagnetite …
网页2024年6月14日 · The crystal structure of magnetite allows titanium atoms to substitute for iron, giving rise to a range of minerals known as titanomagnetites. The internal magnetic structure of titanomagnetite particles in rocks, known as the “domain structure,” controls the ability of that particle to record magnetic fields.
网页Simple titano magnetites contain four species, Fe2 +, Fe 3+ ,Ti4+ and D. In practice, investigators of what might be termed 'near-stoichiometric' titanomagne tites or materials prepared at high temperature at which only a Iimited degree of non-stoichiometry can be supported (Fig. 2.11), generally neglect the presence of vacancies.

网页2018年8月20日 · Titanium-rich titanomagnetites (Fe 3-x Ti x O 4, x > 0.5) and their oxidized equivalents are the main source of magnetic records in submarine basalts and play an important role in paleomagnetism. Fine particles of titanomagnetite in single-domain (SD) or pseudo-single-domain (PSD) states (0.5–20 μm in size) are the dominant carriers of ...
