Origin: A borrowing from German. Etymon: German Titanit.

Etymology: < German Titanit sphene ( M. H. Klaproth Beiträge zur chemischen Kenntniss der Mineralkörper I. (1795) 251); < Titan titan n.² + -it -ite suffix¹); with remodelling after -ite suffix¹.In quot. 1796 at sense 1a, Kirwan applied the name titanite to rutile, apparently influenced by the recent discovery of titanium in that mineral by Klaproth. With sense 2 compare French titanite (1803).

a. Mineralogy. The mineral rutile, which consists of titanium dioxide. Obsolete.

1796 R. Kirwan Elements Mineral. (ed. 2) II. xxiii. 329 Titanite. The Metallic nature of this substance, which many have called a Red Shorl..has been lately discovered by the indefatigable Klaproth.

1812 H. Davy Elements Chem. Philos. 430 Titanium is obtained from a mineral long known by the name of red schorl or titanite.

1853 T. Ross tr. A. von Humboldt Personal Narr. Trav. Amer. III. xxvi. 115 We found some [veins]..full of small fasciculated crystals of rutile titanite.

b. The metal titanium, obtained from the mineral rutile. Obsolete.

1796 G. Pearson in Philos. Trans. (Royal Soc.) 86 426 As for the substances called tungsten, uranite, menackanite, and titanite, we have not yet had sufficient evidence to prove their being peculiar metals.

1799 Monthly Rev. Nov. 349 Among the metals, are overlooked the Tellurite..and Titanite.

2. Mineralogy. A titanium-containing mineral occurring in granitic and metamorphic rocks, often in wedge-shaped crystals, and varying in colour from reddish brown to grey, yellow, and green. Also called sphene.Titanite is a silicate of calcium and titanium, CaTiSiO₅. Small amounts of other elements may be present, including iron, aluminium, and manganese. Crystal system: monoclinic.
