Tā te tikanga
VanAdium: tohu tohu v, ko te maitai hina hiriwa, no te roopu ahorangi 23.9414, ko te Crystal Crystal Crystal, te +4, +2, +2. He tino tiketike te whanganga o Vanadium, me te nuinga o te niobium, ko te kowhatu, ko te malybdenum hei whakarewa. Malfable, he uaua, he kore-a-ringa. He ātete ki te hydrochloric me te waikawa whanariki, ā, he ātete ki te hau, te tote, te ātete wai he pai ake i te nuinga o te kowiri. Ko te whakarewa a Vanadium i roto i te ahua o te ahua ka kaha ake i te pāmahana rūma. Kaore i te taunekeneke ki te hau, te wai, te alkali ranei ka taea te patoi i te waikawa waikawa ko te vanium-grale he maitai-hina. Ko te papa rewa he 1890 ± 10 ℃, ko ia tetahi o nga metara onge me te waahi rewa teitei. He kohua te ahua o te 3380 ° C, ko te van vanuium he uaua, engari kaore i te mangere, engari ki te mea he iti noa te poke, me te hauota.
