A lustrous black to brownish titanium ore, essentially FeTiO3.

[After the Ilmen Mountains, a range of the southern Ural Mountains.]


(Minerals) a black mineral found in igneous rocks as layered deposits and in veins. It is the chief source of titanium. Composition: iron titanium oxide. Formula: FeTiO3. Crystal structure: hexagonal (rhombohedral)
[C19: from Ilmen, mountain range in the southern Urals, Russia, + -ite1]


(ˈɪl məˌnaɪt)

a common black mineral, iron titanate, FeTiO3, an ore of titanium.
[1820–30; after the Ilmen Mountains in the S Urals, where first identified; see -ite1]
