    OverviewStructure and propertiesDiscoveryMineral chemistryParagenesisProcessing and consumptionFeedstock productionLunar ilmenite

    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.

  • Zirconium - Wikipedia

    Zirconium is a chemical element with the symbol Zr and atomic number 40. The name zirconium is taken from the name of the mineral zircon (the word is related to Persian zargun (zircon; zar-gun, "gold-like" or "as gold")), the most important source of zirconium. It is a lustrous, grey-white, strong transition metal that closely resembles hafnium and, to a lesser extent, titanium.
