Taw qhia rau Titanium
Apr 06, 2026| Titanium (Ti), ib qho kev hloov pauv hlau hauv pawg 4 (Titanium subgroup) ntawm Lub Sijhawm 4 ntawm lub sijhawm lub sijhawm, muaj lub cim cim Ti, atomic tooj 22, thiab cov txheeb ze atomic mass ntawm 47.867. Titanium yog ib qho nyuaj, lustrous, silvery- dawb hlau nrog hexagonal -theem thiab cubic -theem. Nws tus txheeb ze ceev yog 4.506, melting point yog 1668 degree, thiab boiling point yog 3287 degree. Nws resistivity yog 42 x 10⁻⁸ Ω·m (20 degree). Hauv qhov xwm txheej, nws feem ntau tshwm sim li rutile, perovskite, thiab ilmenite. Titanium daim txhuam cev tau txais los ntawm kev txo cov titanium tetrachloride nrog magnesium ntawm qhov kub thiab txias, ua raws li melting nrog hluav taws xob arc kom tau txais titanium ingots.
Titanium yog dav faib nyob rau hauv xwm, qeb thib xya nyob rau hauv abundance ntawm metallic ntsiab tom qab txhuas, hlau, calcium, potassium, sodium, thiab magnesium. Hauv cov zaub mov, titanium feem ntau muaj xws li titanium dioxide, titanates, thiab titanium silicates.
Titanium muaj cov khoom zoo heev thiab yog li siv dav. Nws cov haujlwm tseem ceeb suav nrog: aerospace, shipbuilding, tshuaj thiab petrochemical, kev thauj mus los, riam phom, marine, hluav taws xob, kev tsim kho, metallurgy, kev kho mob, khoom ua si, khoom siv niaj hnub thiab kev lag luam teeb.
