Daim ntawv thov

Scandium Hlau yog siv nyob rau hauv ntau yam superalloys uas qhia tau zoo heev metallic kev ua tau zoo nrog lawv lub teeb gravaty. Daim ntawv thov tseem ceeb ntawm Scandium los ntawm qhov hnyav yog nyob rau hauv Scandium-Aluminium alloys rau me me aerospace kev lag luam Cheebtsam. Lawv tau siv nyob rau hauv Lavxias teb sab tub rog aircraft, tshwj xeeb yog MiG-21 thiab MiG-29. 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.
