CAS 7440-62-2 V powder owo Vanadium Powder

Vanadium: aami eroja V, irin grẹy fadaka, jẹ ti ẹgbẹ VB ninu tabili igbakọọkan, nọmba atomiki 23, iwuwo Atomiki 50.9414, okuta kristali ti aarin ti ara, valence ti o wọpọ jẹ +5, +4, +3, +2. Aaye yo ti Vanadium ga pupọ, ati nigbagbogbo pẹlu niobium, tantalum, tungsten, molybdenum bi irin refractory. Malleable, O ti wa ni lile ati ti kii-oofa. O jẹ sooro si hydrochloric ati sulfuric acid, ati pe o jẹ sooro si gaasi, iyọ, Omi resistance jẹ dara ju ọpọlọpọ awọn irin alagbara. Irin Vanadium ni ipo ipon jẹ iduroṣinṣin diẹ sii ni iwọn otutu yara. Ko ṣe ajọṣepọ pẹlu afẹfẹ, omi tabi alkali ati pe o le koju awọn acids dilute Vanadium jẹ irin fadaka-grẹy. Ojuami yo jẹ 1890 ± 10 ℃, eyiti o jẹ ọkan ninu awọn irin toje pẹlu aaye yo giga. O ni aaye gbigbọn ti 3380 ° C, vanadium mimọ jẹ lile, ti kii ṣe oofa, malleable, ṣugbọn ti o ba wa ninu iye diẹ ti awọn impurities, paapaa nitrogen, oxygen, ati hydrogen, le dinku ṣiṣu wọn ni pataki.
