Vanadium hydrogenated
Ka inoa Kina: Vanadium hydride
Vanadium hydride
Hoʻohālikelike Molecular: VH2
Kaupaona Molecular: 55.9812

Vanadium hydride (VH2), ke piʻi ka mahana mai 25 ° C a 200 ° C, piʻi piʻi ke kaomi o ka hydrogen emission mai 0.19 mpa (1.9 atmospheric pressure) i 87 mpa (870 atmospheric pressure), hiki ke ʻōlelo ʻia he compressor kūpono. ʻO Vanadium hydride kahi hydride metala hydride. ʻO nā mea o ka scandium, vanadium, chromium, nickel, palladium, lanthanide a me actinide i nā metala hoʻololi hiki ke hana i nā hui binary me ka hydrogen.
Nā waiwai o vanadium hydride:
(1) kūpaʻa loa ʻo VH2. Ke loaʻa ka mahana 13 ℃, ua hōʻea kāna kaomi hoʻokaʻawale i 1.01 × 105Pa. ʻO 2VH2 → 2VH + H2 kāna hana haʻilula.
(2) ʻO ka hydram vanadium hydride kahi mea metala hina, ma hope o ka omo ʻana o ka hydrogen, hoʻonui latike.
(3) Hydride density is about 6% ~ 10% haʻahaʻa ma mua o ka vanadium metala.
(4) lilo ka vanadium metala ma hope o ke omo o ka hydrogen. Hoʻomehana ʻia i 600 ℃ ~ 700 ℃ i ka holo, decomposed ka hydride o vanadium. Me ka hoʻokuʻu o ka hydrogen, hoʻemi ka paʻakikī o vanadium a hoʻihoʻi ʻia ka waiwai lula.
(5) ʻAʻole pili ia me ka wai, ʻaʻole hoʻi me ka waikawa hydrochloric e paila ana, akā ʻino ʻia e ka waikawa nitric. Hoʻohana ʻia ka Vanadium hydride i ke kinikini mālama hydrogen, nui kona mana mālama hydrogen, kahi hui hoʻohiki.
