The preparation of pure titanium is complicated because the its reactivity. Titanium can not be obtained by the common method of to reduce the oxide v carbon since a an extremely stable carbide is readily produced, and, moreover, the steel is rather reactive toward oxygen and nitrogen in ~ elevated temperatures. Therefore, distinct processes have been devised that, after ~ 1950, adjusted titanium native a laboratory curiosity to crucial commercially produced structural metal. In the Kroll process, one of the ores, such together ilmenite (FeTiO3) or rutile (TiO2), is treated at red warm with carbon and chlorine to productivity titanium tetrachloride, TiCl4, i beg your pardon is fractionally distilled to remove impurities such together ferric chloride, FeCl3. The TiCl4 is then lessened with molten magnesium at about 800 °C (1,500 °F) in an atmosphere of argon, and metallic titanium is produced as a spongy mass native which the excess of magnesium and also magnesium chloride deserve to be eliminated by volatilization at around 1,000 °C (1,800 °F). The sponge may then be fused in an environment of argon or helium in an electrical arc and also be actors into ingots. Top top the laboratory scale, extremely pure titanium can be make by vaporizing the tetraiodide, TiI4, in an extremely pure kind and decomposing that on a hot wire in vacuum. (For treatment of the mining, recovery, and also refining that titanium, see titanium processing. Because that comparative statistics data top top titanium production, see mining.)

Pure titanium is ductile, about fifty percent as thick as iron and less 보다 twice as thick as aluminum; it have the right to be polished to a high lustre. The metal has actually a an extremely low electrical and thermal conductivity and also is paramagnetic (weakly attractive to a magnet). 2 crystal structures exist: below 883 °C (1,621 °F), hexagonal close-packed (alpha); above 883 °C, body-centred cubic (beta). Natural titanium consists of five stable isotopes: titanium-46 (8.0 percent), titanium-47 (7.3 percent), titanium-48 (73.8 percent), titanium-49 (5.5 percent), and also titanium-50 (5.4 percent).


Titanium is vital as an alloying agent with many metals and also some nonmetals. Several of these alloys have actually much higher tensile strengths than go titanium itself. Titanium has terrific corrosion-resistance in plenty of environments since of the formation of a passive oxide surface film. No remarkable corrosion the the metal occurs despite exposure come seawater for much more than 3 years. Titanium resembles other shift metals such together iron and nickel in gift hard and also refractory. Its mix of high strength, low thickness (it is rather light in comparison come other metals of similar mechanical and thermal properties), and also excellent corrosion-resistance do it advantageous for numerous parts of aircraft, spacecraft, missiles, and also ships. It additionally is supplied in prosthetic devices, due to the fact that it does no react through fleshy tissue and also bone. Titanium has additionally been utilized as a deoxidizer in steel and also as an alloying enhancement in countless steels to reduce grain size, in stainless steel to minimize carbon content, in aluminum to filter grain size, and also in copper to produce hardening.

Although at room temperatures titanium is resistant to tarnishing, at elevated temperature it reacts through oxygen in the air. This is no detriment to the properties of titanium throughout forging or fabrication the its alloys; the oxide range is gotten rid of after fabrication. In the fluid state, however, titanium is really reactive and also reduces all well-known refractories.

Titanium is not assaulted by mineral acids at room temperature or by warm aqueous alkali; it disappear in hot hydrochloric acid, offering titanium types in the +3 oxidation state, and also hot nitric acid converts it right into a hydrous oxide the is rather insoluble in mountain or base. The ideal solvents for the steel are hydrofluoric acid or other acids come which fluoride ions have been added; such mediums dissolve titanium and also hold the in solution because of the development of fluoro complexes.
