Below is the article summary. For the full article, see titanium.

titanium , Metallic chemical element, one of the transition elements, chemical symbol Ti, atomic number 22. A silvery gray, lightweight, high-strength, low-corrosion structural metal, it is found combined in almost all rocks and soils and in plants and animals, natural waters, and deep-sea dredgings. Its chief commercial ores are ilmenite and rutile. Its alloys are used for parts for high-speed aircraft, spacecraft, missiles, and ships; in electrodes; in chemical, desalination, and food-handling equipment; and in prostheses. Its compounds, in which it has valence 2, 3, or 4, include titanium trichloride (used as a catalyst in polypropylene production), titanium dioxide (extensively used as a pigment—with the greatest hiding power of all white pigments—in paints, enamels, and lacquers), and titanium tetrachloride (used in skywriting, smoke screens, and as a catalyst).
