Titanium, symbol Ti, silver-white metallic aspect used principally to create light, strong alloys. Titanium is probably the transition factors of the periodic table (see Periodic Legislation). The atomic quantity of titanium is 22.
Titanium was found out in 1791 in the mineral menachanite by the British clergyman William Gregor, who called the brand new component menachite. Four years after, the German chemist Martin Heinrich Klaproth rediscovered the factor in the mineral rutile and called it titanium in allusion to the effectiveness of the mythological Greek Titans. The metal was isolated in 1910.
II. Properties and Occurrence
Pure titanium is soluble in concentrated acids, such as for example sulfuric and hydrofluoric acids, and insoluble in normal water. The metal is incredibly brittle when cold, but is easily malleable and ductile at a minimal red heat. Titanium melts at about 1660. C (about 3020. F), boils at about 3287. C (about 5949. F), and includes a specific gravity of 4.5. The atomic pounds of titanium is 47.88.
Titanium burns in oxygen at 610. C (1130. F) to create titanium dioxide, and it burns in nitrogen at 800. C (1472. F) to create titanium nitride, TiN. Titanium exhibits valences of 4, 3, and 2, and forms the salts titanium tetrachloride, TiCl4; titanium trichloride, TiCl3; and titanium dichloride, TiCl2. It ranks ninth by the bucket load among the factors in the crust of the planet earth but is never within the pure state. It develops as an oxide in the minerals ilmenite, FeTiO3; rutile, TiO2; and sphene, CaO + TiO2+
