Cov ntawv thov no tsis tsuas yog ua kom pom lub luag haujlwm tseem ceeb ntawm scandium oxide nyob rau hauv high-tech teb, tab sis kuj txhawb kev tawg ntawm cov thev naus laus zis.
Los ntawm cov ntaub ntawv kev ua lag luam, raws li tsab ntawv ceeb toom los ntawm Grand View Research, lub ntiaj teb cov khoom lag luam hauv lub xeev cov roj hluav taws xob tau pom muaj kev xav tau ntau ntxiv rau scandium oxide. Txoj kev loj hlob no qhia txog txoj haujlwm tseem ceeb ntawm scandium oxide hauv cov thev naus laus zis tshiab thiab nws cov peev txheej hauv kev daws teeb meem yav tom ntej.
Raws li cov ntaub ntawv tseem ceeb hauv ntiaj teb tsis tshua muaj, scandium oxide ua lub luag haujlwm tsis tuaj yeem hloov pauv hauv cov thev naus laus zis xws li lasers thiab cov roj hluav taws xob hauv lub xeev. Los ntawm cov xwm txheej hauv kev lag luam xws li NASA thiab kev siv tub rog, peb tuaj yeem pom meej tias scandium oxide txhawb kev siv technology li cas. Nyob rau tib lub sijhawm, cov ntaub ntawv kev lag luam kuj qhia tau hais tias nrog kev nce qib ntawm kev siv thev naus laus zis, kev lag luam xav tau rau scandium oxide yuav txuas ntxiv mus. Qhov no tsis tsuas yog coj txoj hauv kev txhim kho rau cov kev lag luam muaj feem xyuam, tab sis kuj tseem muab lub hauv paus ruaj khov rau kev txhim kho high-tech yav tom ntej.
