Titaniyum

Titanium iku unsur kimia sajeroning tabel périodik kang duwé simbol Ti lan nomer atom 22. Logam iki minangka logam transisi kang ènthèng, kuwat, 'lustrous', tahan korosi (kalebu tahan marangp banyu sagara lan chlorine kanthi warna putih-metalik-kaperakan. Titanium digunakaké minangka alloy kuwat lan ènthèng (mligi karo wesi lan aluminum) lan minangka senyawa paling akèh, titanium dioxide, kanggo pigmen putih.

Referensi

Unsur iki tinemu ana ing mineral kanthi sumber utama yaiku rutile lan ilmenite, kang kasebar ing saindhenging bumi. Ana loro wangun allotropic lan lima isotop alami saka unsur iki; Ti-46 nganti Ti-50 lan Ti-48 kang paling akèh tinemu ing alam (73,8%). Salah siji karakteristik Titanium kang paling misuwur yaiku padha kuwaté karo waja nanging mung duwé bobot 60% saka boboté waja. Sipat Titanium mèmper karo zirconium kanthi kimia apa déné fisika. Amarga saka kakuwatané, unsur iki kanggo nggawé peralatan perang (tank) lan pesawat ruang akasa.
