Vanadium hydride (VH2), thaum kub nce li ntawm 25 ° C rau 200 ° C, lub zog ntawm hydrogen emission yuav nce siab ntawm 0.19 mpa (1.9 atmospheric siab) txog 87 mpa (870 atmospheric siab), uas tuaj yeem hais tau tias qhov zoo tagnrho compressor. Vanadium hydride yog kev hloov hlau hlau hydride. Cov ntsiab lus ntawm scandium, vanadium, chromium, npib tsib xee, palladium, lanthanide thiab actinide nyob rau hauv kev hloov hlau tuaj yeem tsim cov binary sib txuas nrog hydrogen.
Cov khoom ntawm vanadium hydride:
(1) VH2 tsis ruaj khov. Thaum twg qhov kub tau yog 13 ℃, nws lub siab tsis sib haum tau mus txog 1.01 × 105Pa. Nws cov tshuaj tiv thaiv yog 2VH2 → 2VH + H2.
(2) Cov hlau vanadium hydride yog grey hlau tshuaj, tom qab kev nqus ntawm hydrogen, ntxaij ntoo nthuav dav.
(3) Cov pa dej hydride yog kwv yees li 6% ~ 10% qis dua cov hlau vanadium.
(4) Cov hlau vanadium ua nkig tom qab kev nqus ntawm hydrogen. Ua kom sov txog 600 ℃ ~ 700 ℃ hauv lub tshuab nqus tsev, hydride ntawm vanadium yog decomposed. Nrog rau kev tso tawm ntawm hydrogen, qhov nyuaj ntawm vanadium poob thiab cov cuab yeej yas rov qab los.
(5) Nws tsis cuam tshuam nrog dej, tsis nrog dej npau npau hydrochloric acid, tab sis yog oxidized los ntawm nitric acid. Vanadium hydride siv nyob rau hauv hydrogen cia alloy, nws lub peev xwm hydrogen cia yog loj, yog ib qho kev cog lus zoo.
