Thortveitite ore
Scandiummuajcov khoom ntawm cov txheeb ze qis (yuav luag sib npaug ntawm txhuas) thiab siab melting point. Scandium nitride (ScN) muaj cov ntsiab lus melting ntawm 2900C thiab siab conductivity, ua rau nws dav siv nyob rau hauv electronics thiab xov tooj cua industries. Scandium yog ib qho ntawm cov khoom siv rau thermonuclear reactors. Scandium tuaj yeem txhawb nqa phosphorescence ntawm ethane thiab txhim kho lub teeb xiav ntawm magnesium oxide. Piv nrog rau cov teeb pom kev siab mercury, scandium sodium teeb muaj qhov zoo xws li lub teeb pom kev zoo thiab lub teeb pom kev zoo, ua rau lawv tsim nyog rau kev ua yeeb yaj kiab thiab plaza teeb pom kev zoo. Scandium tuaj yeem siv los ua ib qho ntxiv rau cov nickel chromium alloys hauv kev lag luam metallurgical los tsim cov hlau tsis muaj cua sov. Scandium yog ib qho tseem ceeb raw khoom rau submarine detection daim hlau. Lub combustion kub ntawm scandium yog mus txog 500C, uas yuav siv tau nyob rau hauv qhov chaw technology. ScN tuaj yeem siv rau kev taug qab xov tooj cua rau ntau lub hom phiaj. Scandium yog qee zaum siv hauv tshuaj.
Scandium feem ntau yog los ntawm scandium vanadium ntxhia. Tongshi tau tsim los ua cov khoom siv raw rau scandium hauv cov tebchaws thiab cheeb tsam xws li Norway, Madagascar, thiab Mozambique. Cov neeg Amelikas tau rov ua dua txhuas phosphate ore.
Thortveitite yog cov ntxhia tsis tshua muaj nyob hauv cov xwm txheej nrog cov peev txheej tsawg. Nyob rau hauv Suav teb, nws yog tsuas yog rov qab los ntawm wolframite, wolframite, wolframite thiab cassiterite concentrate. Wolframite thiab cassiterite muaj SC2O; Txog li 0.4% thiab 0.2%. Rau quartz leeg thiab greisen tso nyiaj uas muaj wolframite, cov ntsiab lus ntawm wolframite series yuav tsum yog 0.02% ~ 0.09% hauv kev lag luam. Rau cassiterite sulfide deposits, kev lag luam xav kom cov ntsiab lus scandium ntawm cassiterite yog 0.02% ~ 0.04%
