Daim ntawv thov ntawm high purity scandium hmoov Sc hmoov nqi CAS No 7440-20-2
Scandium Hlau yog 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 cov khoom hauv lub xeev synthesis ntawm txawv pawg, Sc19Br28Z4, (Z = Mn, Fe, Ru los yog 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.
