Titaniyamu 5

Titaniyamu ndi mankhwala omwe ali ndi chizindikiro cha mankhwala Ti ndi nambala ya atomiki ya 22. Ili mu nthawi ya 4 ndi gulu la IVB la periodic table of chemical elements. Ndizitsulo zoyera zoyera zasiliva zodziwika ndi kulemera kwakukulu, mphamvu zambiri, zitsulo zonyezimira, komanso kukana kunyowa kwa mpweya wa chlorine.

Titaniyamu imatengedwa ngati chitsulo chosowa chifukwa chobalalika komanso chovuta kuchotsa chilengedwe. Koma ndizochuluka, zikuyika chakhumi pakati pa zinthu zonse. Titaniyamu makamaka imaphatikizapo ilmenite ndi hematite, zomwe zimagawidwa kwambiri mu kutumphuka ndi lithosphere. Titaniyamu imapezekanso nthawi imodzi pafupifupi zamoyo zonse, miyala, madzi, ndi dothi. Kuchotsa titaniyamu ku ore akuluakulu kumafuna kugwiritsa ntchito njira za Kroll kapena Hunter. Titaniyamu yodziwika kwambiri ndi titanium dioxide, yomwe ingagwiritsidwe ntchito popanga utoto woyera. Mankhwala ena ndi titanium tetrachloride (TiCl4) (yomwe imagwiritsidwa ntchito ngati chothandizira komanso popanga zowonetsera utsi kapena zolemba zam'mlengalenga) ndi titanium trichloride (TiCl3) (yomwe imagwiritsidwa ntchito kuthandizira kupanga polypropylene).

Titaniyamu ili ndi mphamvu zambiri, yokhala ndi titaniyamu yoyera yokhala ndi mphamvu zofikira mpaka 180kg/mm². Zitsulo zina zimakhala ndi mphamvu zochulukirapo kuposa ma aloyi a titaniyamu, koma mphamvu yeniyeni (chiŵerengero cha mphamvu zowonongeka ndi kachulukidwe) ya titaniyamu imaposa yazitsulo zapamwamba kwambiri. Titanium alloy imakhala ndi kutentha kwabwino, kutentha pang'ono, komanso kulimba kwapang'onopang'ono, chifukwa chake imagwiritsidwa ntchito ngati zida za injini ya ndege ndi roketi ndi zida zopangira zida. Titanium alloy itha kugwiritsidwanso ntchito ngati matanki osungira mafuta ndi oxidizer, komanso zombo zothamanga kwambiri. Panopa pali mfuti zodziwikiratu, zoyikira matope, ndi machubu oombera opanda mphamvu opangidwa ndi aloyi wa titaniyamu. M'makampani amafuta, zotengera zosiyanasiyana, ma reactors, zosinthira kutentha, nsanja za distillation, mapaipi, mapampu, ndi mavavu amagwiritsidwa ntchito kwambiri. Titaniyamu imatha kugwiritsidwa ntchito ngati ma elekitirodi, ma condenser opangira magetsi, komanso zida zowongolera kuwononga chilengedwe. Titanium nickel shape memory alloy yakhala ikugwiritsidwa ntchito kwambiri mu zida ndi mita. Mu mankhwala, titaniyamu angagwiritsidwe ntchito ngati mafupa yokumba ndi zipangizo zosiyanasiyana.
