ilmenite
Sign in to saveIlmenite is a titanium-iron(II) oxide mineral with the idealized formula . It is a weakly magnetic black or steel-gray solid. Ilmenite is the most important ore of titanium and the main source of titanium dioxide, which is used as white pigment in paints, printing inks, fabrics, plastics, paper, sunscreen, food and cosmetics.
AI overview
Ilmenite is a black or steel-gray mineral containing titanium and iron that is weakly magnetic and serves as the primary source of titanium ore. It is economically important because it is processed to produce titanium dioxide, a white pigment widely used in everyday products including paints, plastics, paper, cosmetics, and sunscreen.
