Description
A shiny, black, iron-containing Titanium ore. Ilmenite occurs naturally in many locations in the U.S. (New York, Wyoming), Canada (Quebec), Russia (Ilmen Mountains), Australia, Norway and India. It can also be made synthetically. Ilmenite is used in titanium containing Paint and enamels. For ceramics, ilmenite powder is used as a Glaze color and ilmenite granules are used to produce speckles. Ground ilmenite has been used as a dark colorant in pastels.
