Daim ntawv thovntawmScandium hlau
Scandium hlauyog thov hauv txheej txheem kho qhov muag, catalyst, hluav taws xob ceramics thiab laser kev lag luam. Daim ntawv thov tseem ceeb ntawm scandium los ntawm qhov hnyav yog nyob rau hauvAluminium-scandium alloyS rau cov me aerospace kev lag luam sib xyaw. Qee yam khoom ntawm cov cuab yeej kis las, uas cia siab rau cov khoom ua haujlwm siab, tau ua nrogScandium-txhuas alloysCov. Ua haujlwm hauv cov txheej txheem hauv nroog ntawm cov txheej txheem ntawm cov pawg ntawm cov txheej txheem txawv, SC19BR28Z4, (Z = MN, FE, RU lossis OS). Cov pawg no yog cov paj rau lawv cov qauv thiab cov khoom sib nqus. Nws tseem siv tau los ua kom Super Alloy.Scandium hlauyog siv nyob rau hauv high-tech alloy cov ntaub ntawv, hluav taws xob kev lag luam, teeb tsa cov tub rog, tshuab hluav taws xob, tshuab hluav taws xob nuclearing, thiab lwm daim teb.

Kev npaj kev ntawm scandium hlau:
Scandium hlau yog tsim los ntawm calcium thermal txo.
Chlorination Txoj Kev
Txoj kev chlorination yog ib txoj kev sib xws rau synthesizing scandium hlau. Cov qauv feem ntau suav nrog cov kauj ruam hauv qab no:
Ore access: Ua ntej, cov scandium-muaj ore (xws li scandium bauxite) yog crushed thiab av mus rho tawm cov scandium compound.
Chlorination kev tawm tsam: qhov rho tawm scandium compound reacts nrog chlorine los tsim scandium chloride (SCCL₃).
Txo cov tshuaj tiv thaiv: scandium chloride yog txo los ntawm nws yog xim hlau sodium los yog calcium kom tau txais xim hlau scandium.
Qhov xwm txheej cov kev tawm tsam yog raws li hauv qab no: 2Scf3 + 3ca → 2Sc + 3Caf2
Ntim:Sab hauv txheej ntawm lub tshuab nqus tsev yas, lub tshuab nqus tsev; Lossis lam nrog cov roj sib cav rau kev tiv thaiv. 500g / lub raj mis, 1kg / lub raj mis. lossis ib tus neeg yuav tsum tau ua.
