  • Ilmenite - Wikipedia

    Ilmenite, also known as manaccanite, is a titanium-iron oxide mineral with the idealized formula FeTiO 3.It is a weakly magnetic black or steel-gray solid. From a commercial perspective, ilmenite is the most important ore of titanium. Ilmenite is the main source of titanium dioxide, which is used in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.

  • Ilmenite - an overview ScienceDirect Topics

    The existence of titanium was first recognized in 1791 by William McGregor, an English clergyman and amateur mineralogist, who detected the oxide of an unknown element in local ilmenite sand (FeOTiO 2).A similar observation was made in 1795 by a German chemist, Martin Klaproth, who examined the mineral rutile (TiO 2) and named the element titanium the Titans who, in Greek mythology, were the ...

  • Rutile - Digitalfire

    Rutile is very refractory in oxidation, even a mix of 50% borax alumina-free frit like Ferro 3134 will not melt rutile in a crucible. In reduction, the improvement in melting will depend on the amount of iron present. In ceramic glazes rutile is more often considered a variegator than a colorant.

    is that ilmenite is (mineralogy) a weakly magnetic dark gray mineral found in metamorphic and igneous rocks; it is a mixed oxide of iron and titanium, fetio 3 while rutile is (mineralogy) the most frequent of the three polymorphs of titanium dioxide, crystalizing in the tetragonal system, ti]][[oxygeno 2.

    T. Smijs, S. Pavel, in Nanoengineering, 2015. 2.1 Manufacturing. Ilmenite (FeTiO 3) and rutile (TiO 2) are the most important ores used as raw material for TiO 2.Although natural rutile contains a high amount of TiO 2 with low level of impurities, the mineral is becoming scarce and thus more costly. Consequently, ilmenite is currently favored despite its relatively low TiO 2 content ...
