Vanadium hmoov, V
>> Kev Taw Qhia Prtoduct
Vanadium yog cov nyiaj-grey hlau. Lub ntsiab lus melting yog 1890 + 10Cwhich yog ib qho tsis tshua muaj cov hlau nrog cov nplauv melting. Nws muaj aboiling kis ntawm 3380C, ntshiab vanadium yog nyuaj, tsis-sib nqus thiab tsis txaus, tab sis me me ntawm impurities, tshwj xeeb tshaj yog nitrogen, oxygen thiab hydrogen, tuaj yeem txo nws txoj kev yas.

Vanadium: keeb kwm cim V, nyiaj grey hlau, nyob rau hauv cov lus qhia raws sij hawm belongs rau VB pab pawg, atomic number 23, atomic weight 50.9414, BCC siv lead ua, cov txiaj ntsig feem ntau yog + 5, + 4, + 3, + 2. Vanadium muaj lub siab yaj. taw tes thiab feem ntau hu ua refractory hlau ua ke nrog niobium, tantalum, tungsten thiab molybdenum. Nws yog malleable, nyuaj thiab tsis-sib nqus.
Nws muaj lub peev xwm los tiv thaiv hydrochloric acid thiab sulfuric acid, thiab zoo dua li cov hlau feem ntau hauv cov roj, ntsev thiab dej corrosion tsis kam. Thaum sov sov chav, lub xeev ntom ntawm vanadium yog tus ruaj khov. Nws tsis cuam tshuam nrog huab cua, dej thiab alkali, thiab muaj peev xwm tiv taus dilute acid.Vanadium yog ib qho nyiaj grey hlau. Lub ntsiab lus melting yog 1890 ± 10 ℃, uas yog ib qho tsis tshua muaj hlau nrog cov ntsiab lus kub siab. Nws lub ntsiab lus kub yog 3380 ℃, ntshiab vanadium yog nyuaj, tsis muaj hlau nplaum thiab ductile, tab sis yog tias nws muaj qhov me me ntawm kev ua kom tsis muaj zog, tshwj xeeb tshaj yog nitrogen, oxygen, hydrogen, thiab lwm yam, nws tuaj yeem txo nws txoj kev yas.
