Vanadium hydride (VH2), ha mocheso o phahama ho tloha ho 25 ° C ho isa ho 200 ° C, khatello ea tlhahiso ea haedrojene e tla nyoloha haholo ho tloha ho 0.19 mpa (khatello ea moea ea 1.9) ho isa ho 87 mpa (khatello ea sepakapaka e 870), eo ho ka thoeng ke konpresser e loketseng. Vanadium hydride ke phetoho ea tšepe ea hydride. Likarolo tsa scandium, vanadium, chromium, nickel, palladium, lanthanide le actinide litšepisong tsa phetoho li ka theha metsoako ea binary ka hydrogen.
Thepa ea vanadium hydride:
(1) VH2 ha e tsitsitse haholo. Ha mocheso o le 13 ℃, khatello ea ona ea ho ikarola e fihlile ho 1.01 × 105Pa. Mokhoa oa eona oa karabelo ke 2VH2 → 2VH + H2.
(2) Vanadium hydride ea tšepe ke ntho e putsoa ka tšepe, kamora ho monya ha hydrogen, katoloso ea lekhoakhoa.
(3) Hydride density e ka ba ka 6% ~ 10% e tlase ho feta tšepe ea vanadium.
(4) Metal vanadium e ba brittle kamora ho monya haedrojene. Ho futhumetse ho fihlela ho 600 ℃ ~ 700 ℃ ka lephaka, hydride ea vanadium e ea senyeha. Ha ho lokolloa haedrojene, thatafalo ea vanadium ea fokotseha mme thepa ea polasetiki ea khutlisoa.
(5) Ha e sebelisane le metsi, kapa ha e belisa hydrochloric acid, empa e entsoe oxidized ke nitric acid. Vanadium hydride e sebelisoa ka motsoako oa polokelo ea haedrojene, matla a eona a polokelo ea haedrojene a maholo, ke kompone e tšepisang.
