Ilmenite is a weakly magnetic titanium-iron oxide mineral which is iron-black or steel-gray. It is a crystalline iron titanium oxide (FeTiO3). It crystallizes in the trigonal system, and it has the same crystal structure as corundum and hematite.
Most ilmenite is mined for titanium dioxide production. Finely ground titanium dioxide is a bright white powder widely used as a base pigment in paint, paper and plastics.
Ilmenite sand is also used as a sandblasting agent in the cleaning of diecasting dies.
