Thortveitite macdanta
Scandiumayaa lehsifooyinka cufnaanta qaraabo hoose (ku dhawaad la siman aluminium) iyo barta dhalaalaysa sare. Scandium nitride (ScN) waxay leedahay meel dhalaalaysa oo ah 2900C iyo kororka sare, taas oo ka dhigaysa mid si weyn loogu isticmaalo warshadaha elektiroonigga ah iyo raadiyaha. Scandium waa mid ka mid ah walxaha loogu talagalay reactors thermonuclear. Scandium waxay kicin kartaa fosfooraska ethane waxayna kor u qaadi kartaa iftiinka buluuga ah ee magnesium oxide. Marka la barbar dhigo laambadaha meerkuriyada ee cadaadiska sarreeya, nalalka Scandium sodium waxay leeyihiin faa'iidooyin ay ka mid yihiin waxtarka iftiinka sare iyo midabka iftiinka togan, taasoo ka dhigaysa inay ku habboon yihiin duubista filimada iyo iftiinka plaza. Scandium waxa loo isticmaali karaa wax lagu daro chromium-ka nikkel ee warshadaha birta si loo soo saaro alloys kulaylka sareeyo. Scandium waa shay muhiim ah oo loogu talagalay taarikada ogaanshaha badda hoosteeda. Kuleylka gubashada ee scandium waa ilaa 500C, kaas oo loo isticmaali karo tignoolajiyada hawada sare. ScN waxaa loo isticmaali karaa raadraaca shucaaca sababo kala duwan. Scandium mararka qaarkood waxaa loo isticmaalaa daawada.
Scandium inta badan waxay ka timaadaa macdanta scandium vanadium. Tongshi waxaa loo soo saaray sidii alaabta ceeriin ee scandium ee wadamada iyo gobolada sida Norway, Madagascar, iyo Mozambique. Dadka Maraykanku waxay dib u warshadeeyeen macdanta fosfatetada aluminium.
Thortveitite waa macdan naadir ah oo dabiici ah oo leh kheyraad xaddidan. Shiinaha, waxa inta badan laga soo kabsaday wolframite, wolframite, wolframite iyo cassiterite. Wolframite iyo cassiterite waxay ka kooban yihiin SC2O; Ilaa 0.4% iyo 0.2%. Xididdada quartz iyo dhigaalka greisen ee ay ku jirto wolframite, waxa ku jira taxanaha wolframite waxa looga baahan yahay inay ahaato 0.02% ~ 0.09% warshadaha. Kaydka sulfide cassiterite, warshaduhu waxay u baahan yihiin in maadada scandium ee cassiterite ay noqoto 0.02% ~ 0.04%
