Alloys and Symbols

• Ilmenite, titanic iron, FeTiO₂. with MgTiO₃ and Fe2O₃.
• Octahedrite, TiO₂
• Brookite, TiO₂.
• Rutile, TiO₂.
• Titanite, CaTiSiO₅.

Titanium is a rare element but is quite widely distributed in small quantities. In the form of the minerals rutile and titanite it is present in most igneous rocks. Ilmenite is commonly found in the basic igneous rocks, and is often associated with magnetic iron ores.

Very little titanium is produced in the United States. Rutile deposits occur in Virginia, and some of the Adirondack magnetite deposits contain considerable ilmenite.

The present uses of titanium are rather limited. It has been used in steel and cast iron, in which it serves to eliminate the oxygen and nitrogen. It is also said to give a high tensile strength and great ductility to the steel. It is being used to some extent in the manufacture of electrodes for are lights. The oxide is used to give a yellow color to porcelain, and to give a natural color to false teeth.
