Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide , it can be reduced to produce a lustrous transition metal with a silver color , low density , and high strength, resistant to corrosion in sea water , aqua regia , and chlorine .
Believing this to be a new discovery, Klaproth named it titanium after the Titans of Greek Mythology, but eventually it was clarified that Gregor made the discovery first. Gregor was credited with the discovery, but the element kept the name chosen by Klaproth. Gregor later found titanium in corundum from Tibet, and in a tourmaline from a local ...
Klaproth independently discovered cerium (1803), a rare earth element, around the same time as Jöns Jacob Berzelius and Wilhelm Hisinger, in the winter of 1803. [17] William Gregor of Cornwall was the first to identify the element titanium in 1791, correctly concluding that he had found a new element in the ore ilmenite from the Menachan ...
Titanium dioxide, also known as titanium(IV) oxide or titania / t aɪ ˈ t eɪ n i ə /, is the inorganic compound derived from titanium with the chemical formula TiO 2. When used as a pigment, it is called titanium white, Pigment White 6 (PW6), or CI 77891. [4] It is a white solid that is insoluble in water, although mineral forms can appear ...
André-Louis Debierne had previously (in 1899 and 1900) reported the discovery of a new element actinium that was supposedly similar to titanium and thorium, which cannot have included much actual element 89. But by 1904, when Giesel and Debierne met, both had samples containing element 89, and so Debierne has generally been given credit for ...

It has a chemical composition of 6% aluminum, 4% vanadium, 0.25% (maximum) iron, 0.2% (maximum) oxygen, and the remainder titanium. [19] It is significantly stronger than commercially pure titanium (grades 1-4) while having the same stiffness and thermal properties (excluding thermal conductivity, which is about 60% lower in Grade 5 Ti than in ...
