Vanadium Hydride ufa, VH2

Vanadium hydride (VH2), kutentha kukakwera kuchokera ku 25 ° C mpaka 200 ° C, kuthamanga kwa kutulutsa kwa hydrogen kumakwera kwambiri kuchokera pa 0.19 mpa (1.9 kuthamanga kwa m'mlengalenga) mpaka 87 mpa (kuthamanga kwa mumlengalenga 870), komwe titha kunena kuti ndi kompresa wabwino.

Vanadium hydride (VH2), kutentha kukakwera kuchokera ku 25 ° C mpaka 200 ° C, kuthamanga kwa kutulutsa kwa hydrogen kumakwera kwambiri kuchokera pa 0.19 mpa (1.9 kuthamanga kwa m'mlengalenga) mpaka 87 mpa (kuthamanga kwa mumlengalenga 870), komwe titha kunena kuti ndi kompresa wabwino. Vanadium hydride ndichosintha chitsulo hydride. Zinthu za scandium, vanadium, chromium, nickel, palladium, lanthanide ndi actinide pakusintha kwazitsulo zimatha kupanga mankhwala a binary ndi hydrogen.
Katundu wa vanadium hydride:
(1) VH2 ndiyosakhazikika kwambiri. Kutentha kukakhala 13 ℃, mphamvu yake yodzipatula yafika 1.01 × 105Pa. Zomwe zimayendera ndi 2VH2 → 2VH + H2.
(2) Chitsulo cha vanadium hydride ndichinthu chofiirira, pambuyo poti mayikidwe a hydrogen ayambe kukula.
(3) Kuchulukana kwa Hydride kuli pafupifupi 6% ~ 10% poyerekeza ndi chitsulo cha vanadium.
(4) Chitsulo vanadium chimakhala chofooka pambuyo mayamwidwe hydrogen. Kutenthedwa mpaka 600 ℃ ~ 700 ℃ muzingalowe, hydride ya vanadium imawonongeka. Pakutulutsa hydrogen, kuuma kwa vanadium kumachepa ndipo katundu wa pulasitiki abwezeretsedwanso.
(5) Sichiyanjana ndi madzi, kapena ndi madzi otentha a hydrochloric acid, koma imakhazikika ndi nitric acid. Vanadium hydride imagwiritsidwa ntchito mu aloyi wa haidrojeni yosungira, mphamvu yake yosungira haidrojeni ndi yayikulu, ndi gulu lolonjeza.
