vanadium silicide, VSi2

Nws yog xim hlau prismatic siv lead ua. Qhov txheeb ze ntom ntom yog 4.42. Insoluble hauv col dej thiab dej kub, soluble hauv hydrofluoric acid, insoluble hauv ethanol, ether thiab acid. Txoj kev: raws li qhov sib piv Qhov sib piv ntawm vanadium pentoxide rau silicon reacts ntawm 1200 ℃, los yog yuav sib npaug rau cov hlau Vanadium tuaj yeem tau los ntawm cov tshuaj tiv thaiv ntawm vanadium nrog silicon ntawm kev kub.

Siv cov mis tshuaj VSi2. molecular phaus 107.11。 Nws yog xim hlau prismatic siv lead ua. Qhov ceev ceev ntawm tus txheeb ze yog 4.42. Insoluble hauv dej txias thiab dej kub, soluble hauv hydrofluoric acid, insoluble hauv ethanol, ether thiab acid. Txoj kev: raws li qhov sib piv Qhov sib piv ntawm vanadium pentoxide rau siliconreacts ntawm 1200 ℃, lossis yuav tsum sib npaug rau cov hlau Vanadium tuaj yeem tau los ntawm cov tshuaj tiv thaiv ntawm vanadium nrog silicon ntawm kev kub. Daim ntawv thov: siv rau kev tiv thaiv acid thiab hluav taws ua hauj
Khoom Siv Science.

1.Preparation ntawm vanadium silicide nyias zaj duab xis. Nyias txheej silicides nrog cov khoom zoo ua tau ncaj qha los ua ke los ntawm implantation ntawm vanadium hlau ions nrog qhov siab ntom ntom. Nrog rau qhov nce ntawm qhov ntom ntom ntom nti, vanadium silicide theem loj hlob tuaj, thiab daim ntawv tiv thaiv Rs ntawm daim nyias nyias txo kev poob qis. Thaum cov kab teeb ntom ntom ntom ntab yog 25 μ A / cm2, RS nce mus txog qhov tsawg kawg nkaus tus nqi ntawm 22 ψ, uas qhia tau hais tias kev tsim cov tshuaj txuas ntxiv tau tsim. Kev soj ntsuam xoo hluav taws xob tsom tau pom tias plaub yam ntawm vanadium silicides, suav nrog V3Si, V5Si3, V3Si5 thiab VSi2, tau tsim hauv txheej txheej cog. Tom qab annealing, RS txo qis zuj zus, qhov tsawg kawg nkaus rs tuaj yeem txo mus rau 9 ψ, thiab qhov thev taus tuaj yeem ua kom tsawg li 72 ψ ψ m, uas qhia tau tias qhov zoo ntawm vanadium silicide nyias txheej tau ntxiv txhim kho. Tom qab lub siab ntom ntom txhaj tshuaj thiab annealing, vanadium silicide theem hlob ntxiv. Kev ntsuas qhov ntom ntom ntom ntom ntom ntom thiab qhov kub thiab qhov siab tshaj qhov siab (1200 ℃) stil.

2. Vanadium silicide yog hom suab zoo nqus cov khoom siv ceramic. Qhov txheej txheej saum npoo nrog cov suab zoo ib yam yog coated rau saum npoo ntawm txheej txheej.
