CAS 7440-62-2 V hmoov nqe Vanadium Powder
Product Description
Kev taw qhia luv luv
Khoom npe: Vanadium V Powder
Purity: 99% min
CAS Nr .: 7440-62-2
Particle loj: 325 mesh
Yam ntxwv.
Vanadium: lub cim cim V, nyiaj grey hlau, belongs rau VB pawg nyob rau hauv lub sij hawm lub rooj, atomic tooj 23, Atomic hnyav 50.9414, lub cev centered cubic siv lead ua, feem ntau valence yog +5, +4, +3, +2.Vanadium lub melting point yog siab heev, thiab feem ntau nrog niobium, tantalum, tungsten, molybdenum li refractory hlau.Malleable, Nws yog ib qho nyuaj thiab tsis muaj hlau nplaum.Nws yog resistant rau hydrochloric thiab sulfuric acid, thiab yog resistant rau roj, ntsev, dej kuj yog zoo dua li feem ntau stainless hlau.Vanadium hlau nyob rau hauv lub xeev tuab yog ruaj khov nyob rau hauv chav tsev kub.Nws tsis cuam tshuam nrog huab cua, dej lossis alkali thiab tuaj yeem tiv taus dilute acids Vanadium yog cov nyiaj-grey hlau.Lub melting point yog 1890 ± 10 ℃, uas yog ib qho ntawm cov hlau tsis tshua muaj siab melting point.Nws muaj qhov kub kub ntawm 3380 ° C, ntshiab vanadium yog ib qho nyuaj, tsis yog-sib nqus, malleable, tab sis yog tias muaj me me ntawm impurities, tshwj xeeb tshaj yog nitrogen, oxygen, thiab hydrogen, tuaj yeem txo lawv cov plasticity.
