Vanadium hydride (VH2), kana tembiricha ikakwira kubva pa25 ° C kusvika 200 ° C, kumanikidzwa kwehydrogen kubuda kuchakwira zvakanyanya kubva pa0.99 mpa (1.9 mhepo yekudenga) kusvika 87 87 (870 mhepo yekudenga), iyo inogona kunzi ndeye compressor yakanaka. Vanadium hydride ishanduko yesimbi hydride. Izvo zvinhu zve scandium, vanadium, chromium, nickel, palladium, lanthanide uye actinide mune shanduko simbi dzinogona kuumba zvigadzirwa zvebhinari nehydrogen.
Zvivakwa zvevanadium hydride:
(1) VH2 haina kugadzikana. Kana iyo tembiricha iri 13 ℃, yayo dissociation kumanikidza yasvika 1.01 × 105Pa. Maitiro ayo maitiro 2VH2 → 2VH + H2.
(2) Iyo simbi vanadium hydride ndeye grey simbi chinhu, mushure mekumwa kwehydrogen, kuwedzera lattice.
(3) Hydride density ingangoita 6% ~ 10% yakaderera pane vanadium simbi.
(4) Simbi vanadium inova inopwanya mushure mekumwa kwehydrogen. Inopisa kusvika pa600 ℃ ~ 700 ℃ muvharumu, iyo hydride yevanadium yakaora. Nekusunungurwa kwehydrogen, kuomarara kwevanadium kunoderera uye chivakwa chepurasitiki chakadzorerwa.
(5) Haibatanidze nemvura, kana nekubika hydrochloric acid, asi inosanganiswa ne nitric acid. Vanadium hydride inoshandiswa muhydrogen kuchengetedza alloy, ayo ehydrogen ekuchengetedza masimba akakura, inzvimbo inovimbisa.
