How Is Titanium Made?
· Perovskite (CaTiO3) and sphene (CaTiSiO5) are calcium and titanium ores. Neither of these materials are used in the commercial production of titanium due to the difficulty in removing the calcium. In the future, it is likely that perovskite may be used commercially, as it contains nearly 60% titanium dioxide and only has calcium as an impurity.
