Zoo siab 99.9% - 99.9999% Sc pob Scandium hlau CAS 7440-20-2
Scandium, ib hom hlau hloov pauv tsis tshua muaj nrog tus lej atomic ntawm 21, yog ntau tshaj li ib qho khoom siv hauv lub rooj periodic; nws muaj peev xwm loj heev thiab tab tom txhais dua cov qauv kev ua tau zoo hauv aerospace, automotive, cov khoom siv kis las thiab ntau ntxiv.
Cov hlau scandium ntshiab yooj yim sib xyaw nrog oxygen, carbon dioxide thiab dej thaum raug cua ncaj qha, yog li nws yuav tsum tau kaw nrog roj argon. Scandium oxide, uas yog dawb thiab tsis yaj hauv dej, yog pom ntau dua hauv kev ua lag luam. Scandium muaj ntau yam khoom zoo dua, xws li qhov siab dua melting point (1541 ℃) dua li hlau, nickel, lub ntiaj teb tsis tshua muaj lanthanum, cerium, praseodymium thiab neodymium, thiab lwm yam, thib ob tsuas yog rau cov ntsiab lus kub siab ntawm rhenium (5627 ℃), molybdenum (5560 ℃) thiab cobalt (2870 ℃). Tib lub sijhawm, scandium, ua tus tswv cuab sib dua ntawm tsev neeg tsis tshua muaj ntiaj teb, muaj cov yam ntxwv ntawm qhov ceev qis, ductility zoo, kev ua tau zoo catalytic zoo heev thiab lwm yam.
Hlau Scandium yog tsim los ntawm kev txo cov calcium thermal. Cov qauv tshuaj tiv thaiv yog raws li nram no: 2ScF3 + 3Ca → 2Sc + 3CaF2
Kev tsav dav hlauCov chaw ua dav hlau yog ib qho ntawm cov neeg tau txais txiaj ntsig tseem ceeb ntawm cov hlau scandium. Cov chaw tsim khoom dav hlau tab tom siv cov hlau scandium aluminium rau hauv lawv cov qauv tsim kom txo qhov hnyav yam tsis muaj kev cuam tshuam rau lub zog. Qhov no ua rau cov dav hlau siv roj tsawg dua, nrog rau kev mus deb dua thiab kev thauj khoom ntau dua. Kev siv cov scandium kuj tseem tuaj yeem txhim kho kev tiv thaiv kev nkees ntawm cov khoom, ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm kev ya dav hlau.
TshebKev lag luam tsheb kuj maj mam paub txog lub peev xwm ntawm scandium. Thaum cov chaw tsim khoom siv zog ua kom tau raws li cov qauv kev siv roj tsawg thiab txo cov pa phem, qhov kev thov rau cov khoom siv sib dua tab tom loj hlob. Scandium tuaj yeem siv los tsim cov khoom siv tsheb zoo xws li lub log, thav duab thiab cov khoom siv cav, yog li txhim kho qhov zoo ntawm kev sib tw hauv kev ua tau zoo thiab kev ua haujlwm zoo.
Cov khoom siv kis las: Scandium lub cev nyhav sib dua thiab muaj zog ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv kis las ua tau zoo. Txij li cov thav tsheb kauj vab mus rau cov khoom siv golf, kev ntxiv scandium tuaj yeem txhim kho kev ua tau zoo thiab txo qhov hnyav, pab cov neeg ncaws pob ua tau zoo tshaj plaws. Qhov ruaj khov ntawm scandium-aluminium alloys kuj txhais tau tias cov khoom siv tuaj yeem tiv taus kev siv hnyav, muab lub neej ua haujlwm ntev thiab kev ntseeg siab.
Kev Tiv ThaivHauv kev tiv thaiv teb chaws, kev ua tau zoo thiab kev ntseeg tau yog qhov tseem ceeb heev, thiab cov hlau scandium siv rau ntau qhov chaw, suav nrog cov dav hlau tub rog thiab cov tsheb tub rog uas muaj riam phom. Cov khoom siv sib dua ntawm cov hlau scandium aluminium ua rau muaj kev txav mus los thiab kev ua haujlwm zoo dua ntawm thaj chaw sib ntaus sib tua, thaum nws lub zog kuj ua kom muaj kev tiv thaiv thiab kev ruaj khov.
Kev luam ntawv 3DKev nce qib ntawm cov thev naus laus zis tsim khoom ntxiv tau qhib txoj hauv kev tshiab rau kev siv scandium. Scandium-aluminium alloys tab tom raug tshawb nrhiav rau 3D luam ntawv daim ntawv thov, qhov twg lawv cov khoom tshwj xeeb tuaj yeem siv los tsim cov geometries nyuaj uas yog ob qho tib si sib dua thiab muaj zog heev. Qhov kev tsim kho tshiab no tau qhib txoj hauv kev rau cov qauv tsim tshiab thiab cov ntawv thov uas yav dhau los tsis tau ua tiav.
