TITANIUM

Ti. Atomic Weight 48.1. <A metallic element related to Zirconium, Cerium and Thorium, First discovered in 1791 by W. McGregor in the mineral me nach a nite or ilmenite, a magnetic sand found in Cornwall, England. The metal was first isolated by Berzelius in 1825. It occurs in the combined state in most sands, clays and granite, and it has been found in mineral waters, plants and elsewhere. It is, therefore, widely distributed but occurs in small quantities. It occurs as a grey amorphous powder, or as a very hard solid, having a brilliant waite fracture. It can also be obtained in yellow scales with a bluish surface color. It has a specific gravity of 4.87 and melts at 1795° OC. It is used in the steel industry, titanium steel being employed to a large extent for bridge construction and on railroads. THERIUM,
