vanadium silicide, VSi2

Chitsulo chachitsulo chachitsulo. Kuchuluka kwake kunali 4.42. Osasungunuka m'madzi amtundu ndi madzi Otentha, osungunuka mu hydrofluoric acid, osasungunuka ndi ethanol, ether ndi acid. Njira: molingana ndi machesi Kuwerengera kwa vanadium pentoxide ndi silicon kumayambira 1200 ℃, kapena kungafanane ndi chitsulo Vanadium chitha kupezeka poyankha vanadium ndi silicon pakatenthedwe.

Njira yopangira mankhwala VSi2. maselo kulemera 107.11。 Metallic prismatic crystal. Kuchuluka kwake kunali 4.42. Sungasungunuke m'madzi ozizira ndi Madzi otentha, sungunuka mu hydrofluoric acid, osasungunuka ndi ethanol, ether ndi acid. Njira: molingana ndi machesi Chiwerengero cha vanadium pentoxide ndi silicon chimakhudzanso 1200 ℃, kapena chikhala chogwirizana ndi chitsulo Vanadium chitha kupezeka poyankha vanadium ndi silicon pakatenthedwe. Ntchito: ntchito asidi kukana ndi moto kukana
Sayansi Yachilengedwe.

1. Kukonzekera kwa vanadium silicide mafilimu owonda. Silicides wosanjikiza wokhala ndi katundu wabwino amatha kuphatikizidwa mwachindunji ndikukhazikitsidwa kwa ayoni zitsulo zazitsulo zokhala ndi mulingo wokwera kwambiri. Ndikukula kwa kachulukidwe ka mtengowu, gawo la vanadium silicide limakula, ndipo pepala losakanizika la silidi wochepa limachepa. Pamene makulidwe amtengowo ali 25 μ A / cm2, RS ifika pamtengo wotsika wa 22 ψ, zomwe zikuwonetsa kuti silicide mosalekeza yapangidwa. Kusanthula kwa X-ray kudawonetsa kuti mitundu inayi ya ma vanidisidi a vanadium, kuphatikiza V3Si, V5Si3, V3Si5 ndi VSi2, adapangidwa mosanjikiza. Pambuyo powonjezera, RS imachepa mwachidziwikire, ma rs ochepera amatha kuchepetsedwa kukhala 9 ψ, ndipo kuyimitsidwa kumatha kutsika ngati 72 μ ψ m, zomwe zikuwonetsa kuti mtundu wa vanadium silicide wosanjikiza wocheperako wakula bwino. Pambuyo pa jekeseni wa mulingo wokwera kwambiri ndikulumikiza, gawo la vanadium silicide limakulabe. Jekeseni yayikulu yamitengo komanso kutentha kwambiri (1200 ℃) stil.

2. Vanadium silicide ndi mtundu wa phokoso lotenga zinthu za ceramic. Chosanjikiza chakumtunda chokhala ndi katundu wolanda chimakutidwa pamwamba pake.
