Ilmenite is a common accessory mineral found in metamorphic and igneous rocks. It is found in large concentrations in ultramafic to mafic layered intrusions where it forms as part of a cumulate layer within the silicate stratigraphy of the intrusion. Ilmenite generally occurs within the pyroxenitic portion of such intrusions (the 'pyroxene-in ...

Abstract Titanium carbide (TiC) powder was combustion-synthesized in argon from mineral ilmenite and activated carbon (C) using magnesium (Mg) as a fuel. The reactant powders were taken at FeTiO3 : C : Mg molar ratios of 1 : 1 : 3 and 1 : 1.5 : 4.5. The as-combusted products were leached with 1 M HCl at 80 or 90°C to remove byproducts and impurities. Best results (fewer …

Ilmenite is a black iron-titanium oxide with a chemical composition of FeTiO 3. Ilmenite is the primary ore of titanium, a metal needed to make a variety of high-performance alloys. Most of the ilmenite mined worldwide is used to manufacture titanium dioxide, TiO 2, an important pigment, whiting, and polishing abrasive. ADVERTISEMENT

Ilmenite: Ilmenite is a dense, black metallic mineral that, when rubbed across a rough hard surface, exhibits a black streak similar to that of magnetite. As ilmenite is not magnetic, a magnet can be used to distinguish pure samples of the two. Some ilmenite samples appear weakly magnetic, however, due to inter-grown magnetite crystals.

Ilmenite. A common accessory mineral in igneous rocks, ilmenite was named after its type locality in the Ilmen Mountains in Russia. It is a major source of titanium, which is used principally in the manufacture of paint and as a structural material because of its high strength-to-weight ratio.

Ilmenite is an economically important and interesting mineral. It is named for its place of discovery (such places are called type localities) at Ilmen Lake in the Ilmen Mountains, Miask in the southern portion of the Ural Mountains of Russia. Ilmenite forms as a primary mineral in mafic igneous rocks and is concentrated into layers by a process called"magmatic segregation".
