What is "titanium"

Titanium \Ti*ta"ni*um\, n. [NL., fr. L. Titani or Titanes, Gr. ?, the sons of the earth.] (Chem.) An elementary substance found combined in the minerals manaccanite, rutile, sphene, etc., and isolated as an infusible iron-gray amorphous powder, having a metallic luster. It burns when heated in the air. Symbol Ti. Atomic weight 48.1.

metallic element, 1796, Modern Latin, named in 1795 by German chemist and mineralogist Martin Heinrich Klaproth (1743-1817) from Latin Titan (see titan) as "sons of the earth." He previously had named uranium. A pure specimen was not isolated until 1887.

n. 1 A chemical element, atomic number 22; it is a strong, corrosion-resistant transition metal, used to make light alloys for aircraft etc. 2 (cx countable English) A single atom of this element.

n. a light strong gray lustrous corrosion-resistant metallic element used in strong light-weight alloys (as for airplane parts); the main sources are rutile and ilmenite [syn: Ti, atomic number 22]

Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia, and chlorine.

Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and named by Martin Heinrich Klaproth for the Titans of Greek mythology. The element occurs within a number of mineral deposits, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere, and it is found in almost all living things, rocks, water bodies, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide, is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl), a component of smoke screens and catalysts; and titanium trichloride (TiCl), which is used as a catalyst in the production of polypropylene.

Titanium can be alloyed with iron, aluminium, vanadium, and molybdenum, among other elements, to produce strong, lightweight alloys for aerospace ( jet engines, missiles, and spacecraft), military, industrial process (chemicals and petro-chemicals, desalination plants, pulp, and paper), automotive, agri-food, medical prostheses, orthopedic implants, dental and endodontic instruments and files, dental implants, sporting goods, jewelry, mobile phones, and other applications.

The two most useful properties of the metal are corrosion resistance and the highest strength-to-density ratio of any metallic element. In its unalloyed condition, titanium is as strong as some steels, but less dense. There are two allotropic forms and five naturally occurring isotopes of this element, Ti through Ti, with Ti being the most abundant (73.8%). Although they have the same number of valence electrons and are in the same group in the periodic table, titanium and zirconium differ in many chemical and physical properties.

Titanium is a chemical element.

Native titanium (IMA2010-044) is a natural occurrence of titanium. Its type locality is the Luobusa mining district, Luobusha fault zone ( Yarlung Zangbo suture zone), Qusum County, Shannan, Tibet.

"Titanium" is a song by French DJ and music producer David Guetta, featuring vocals by Australian recording artist Sia. Taken from Guetta's fifth studio album, Nothing but the Beat, the song was written by Sia, Guetta, Giorgio Tuinfort and Afrojack. Production was also handled by Guetta, Tuinfort and Afrojack. "Titanium" was initially released for digital download on August 8, 2011, as the first of four promotional singles from the album. It was later released as the album's fourth single in December 2011. The song originally featured the vocals of American recording artist Mary J. Blige, whose version of the song leaked online in July 2011.

"Titanium" is a ballad which draws from the genres of house, pop and urban- dance. The song's lyrics are about inner strength. Sia's vocals on "Titanium" received comparisons to those by Fergie and the song was also musically compared to Coldplay's work. Critics were positive towards the song and noted it as one of the standout tracks from Nothing but the Beat. "Titanium" attained top 10 positions in several major music markets, including Australia, Austria, Denmark, Finland, France, Germany, Hungary, Ireland, Italy, The Netherlands, New Zealand, Norway, Spain, Sweden, Switzerland and the United States. In the United Kingdom, it peaked at number one, becoming Guetta's fifth number-one single on the chart and Sia's first.

The song's accompanying music video premiered on December 21, 2011 but does not feature appearances by Guetta or Sia. Instead, the video focuses on a young boy, played by actor Ryan Lee, with supernatural powers. Along with other songs, "Titanium" was pulled from radio stations in the US after the Sandy Hook Elementary School shooting.

Titanium is a New Zealand pop boy band formed in Auckland in 2012 from the winners of The Edge radio station's competition to create New Zealand's second boy band. The Edge radio station hosted auditions across New Zealand and eventually six young men were selected for the group consisting of members, Zac Taylor, Andrew Papas, Jordi Webber, Shaquille Paranihi-Ngauma, Haydn Linsley and T.K Paradza. They released their debut single, "Come On Home". The single debuted at number one on the official New Zealand Singles Chart on 17 September 2012. Titanium released their debut studio album, All For You in December 2012. They became the first New Zealand band to have three songs in the Top 40 Singles Chart at one time.
