Ilmenite is a titanium-iron oxide mineral with the idealized formula FeTiO 3. It is a weakly magnetic black or steel-gray solid. Ilmenite is the most important ore of titanium[5] and the main source of titanium dioxide, which is used in paints, printing inks,[6] fabrics, plastics, paper, sunscreen, food and cosmetics.[7]
