vanadium silicide, VSi2

Metallic prismatic kristale. Boima ba eona e ne e le 4.42. Ha e kenelle ka metsing a col le metsi a chesang, a qhibilihang ka har'a hydrofluoric acid, e sa qhibilihang ka har'a ethanol, ether le acid. Mokhoa: ho latela papali Karo-karolelano ea vanadium pentoxide le silicon e itšoara ka 1200 ℃, kapa e tla ba ho lekana le Vanadium ea tšepe e ka fumanoa ka karabelo ea vanadium le silicon mocheso o phahameng.

Morero oa lik'hemik'hale VSi2. Boima ba limolek'hule 107.11. Metallic prismatic crystal. Boima ba eona e ne e le 4.42. Ha e kenelle ka metsing a batang le metsing a chesang, e qhibilihang ka har'a hydrofluoric acid, e sa qhibilihe ka har'a ethanol, ether le acid. Mokhoa: ho latela papali Karo-karolelano ea vanadium pentoxide ho silicon e arabela ka 1200 ℃, kapa e tla ba ho lekana le Vanadium ea tšepe e ka fumanoa ka karabelo ea vanadium le silicon mocheso o phahameng. Kopo: sebelisoa bakeng sa ho hanyetsa acid e le ho hanyetsa mollo
Boitsebiso ba Saense.

1.Lokiso ea lifilimi tse tšesaane tsa vanadium silicide. Li-silicide tse tšesaane tse nang le thepa e ntle li ka hlophisoa ka kotloloho ka ho kenngwa ha li-ion tsa tšepe tse nang le palo e phahameng ea toloki. Ka keketseho ea letsoalo, karolo ea vanadium silicide ea hola, 'me ho hanyetsa li-sheet tsa li-silide tse tšesaane ho fokotseha ka ho hlaka. Ha palo ea toloki e le 25 μ A / cm2, RS e fihlela boleng bo tlase ba 22 ψ, e bontšang hore silicide e tsoelang pele e se e entsoe. Tlhahlobo ea phallo ea X-ray e bontšitse hore mefuta e mene ea li-silicone tsa vanadium, ho kenyeletsoa V3Si, V5Si3, V3Si5 le VSi2, li thehiloe ka lera le kentsoeng. Kamora ho koaloa, RS e fokotseha ka ho hlaka, li-rs tse tlase li ka fokotsoa ho ba 9 ψ, 'me resistivity e ka ba tlase ho 72 μ ψ m, e bonts'ang hore boleng ba vanadium silicide lera le lesesaane bo ntlafalitsoe. Kamora ho entoa ka bongata ba molamu le ho tlatsoa, ​​karolo ea vanadium silicide e ea hola. Ho entoa ka palo e phahameng ea boriti le ho kenya mocheso o phahameng (1200 ℃)

2. Vanadium silicide ke mofuta oa lintho tse entsoeng ka letsopa tse amohelang molumo. Lera le kaholimo le thepa e amohelang molumo le koahetsoe ka holim'a mokato oa motheo.
