Cov tsos mob: Silver grey hlau ingot, spongy, koob zoo li tus, silvery dawb metallic luster, tuaj yeem txiav raws li cov neeg siv khoom xav tau
Cov yam ntxwv ntawm lub cev: Cov khoom yog dawb dawb, feem ntau yog nyob rau hauv daim ntawv ntawm distilled crystalline blocks (tawv nqaij zoo li) ntawm hlau.Castings, sponge blocks, los yog lo ntsiab muag kuj tuaj yeem ua rau hauv daim ntawv khawm zoo li cov castings, nrog rau qhov chaw huv si. Yooj yim rau yaj hauv dej, tuaj yeem hnov mob nrog dej kub, thiab yooj yim tsaus rau saum huab cua.
Daim ntawv thov:
Scandium hlauyog siv rau hauv optical txheej, catalyst, hluav taws xob ceramics thiab laser kev lag luam.Daim ntawv thov tseem ceeb ntawm Scandium los ntawm qhov hnyav yog nyob rau hauv Aluminium-Scandium alloys rau me me aerospace kev lag luam Cheebtsam.Qee cov khoom ntawm cov khoom siv kis las, uas tso siab rau cov khoom siv ua haujlwm siab, tau ua nrog Scandium-Aluminium alloys.Ua hauj lwm hauv lub xeev cov khoom sib txuas ntawm cov pawg txawv txawv, Sc19Br28Z4, (Z = Mn, Fe, Ru lossis Os).Cov pawg no muaj kev txaus siab rau lawv cov qauv thiab cov khoom sib nqus.Nws kuj yog siv los ua super alloy.Scandium hlau yog siv nyob rau hauv high-tech alloy cov ntaub ntawv, hluav taws xob lub teeb qhov chaw, roj cell industries, nuclear zog industries, thiab tub rog industriesScandium hlau yog dav siv nyob rau hauv aerospace, electronics kev lag luam, teeb pom kev zoo, catalysis, nuclear technology, superconducting technology, thiab lwm yam.
