Piv nrog yttrium thiab lanthanide, scandium hlau muaj ib lub vojvoog ion me me heev thiab tsis muaj zog alkalinity ntawm hydroxides. Yog li ntawd, thaum scandium thiab cov ntsiab lus tsis tshua muaj hauv ntiaj teb sib xyaw ua ke, lawv tau kho nrog ammonia (los yog alkali dilute heev), thiab scandium yuav raug precipitated ua ntej. Yog li ntawd, nws tuaj yeem yooj yim cais tawm ntawm lub ntiaj teb tsis tshua muaj los ntawm kev siv "qib nag lossis daus" txoj kev. Lwm txoj kev yog siv cov polar decomposition ntawm nitrate rau kev sib cais. Vim tias scandium nitrate yooj yim rau decompose, lub hom phiaj ntawm kev sib cais yog tiav.
Scandium hlau tuaj yeem npaj los ntawm electrolysis. ScCl3, KCl thiab LiCl yog co melted thaum lub sij hawm scandium smelting, thiab cov zinc molten yog siv los ua cathode rau electrolysis cais scandium ntawm zinc electrode, thiab ces zinc yog evaporated kom tau scandium hlau. Tsis tas li ntawd, scandium tuaj yeem rov qab tau yooj yim thaum ua cov ore los tsim cov uranium, thorium thiab lanthanide. Kev rov qab zoo ntawm scandium cuam tshuam nrog tungsten thiab tin ores kuj yog ib qho tseem ceeb ntawm scandium. Scandium feem ntau yog nyob rau hauv 3-valent xeev nyob rau hauv lub compound, uas yog ib qho yooj yim rau oxidized rau Sc2O3 nyob rau hauv cov huab cua thiab poob nws cov xim hlau luster thiab ua tsaus grey.
Scandium reacts nrog dej kub kom tso tawm hydrogen, uas yog soluble nyob rau hauv acid thiab yog ib tug muaj zog txo tus neeg sawv cev. Scandium oxides thiab hydroxides tsuas yog alkaline, tab sis lawv cov tshauv ntsev tsis tuaj yeem ua rau hydrolyzed. Scandium chloride yog siv lead ua dawb, yooj yim soluble hauv dej thiab deliquescent hauv huab cua. Hauv kev lag luam metallurgical, scandium feem ntau yog siv los ua cov alloys (alloy additives) los txhim kho lub zog, hardness, kub tsis kam thiab kev ua tau zoo ntawm alloys. Piv txwv li, ntxiv ib qho me me ntawm scandium rau molten hlau tuaj yeem txhim kho cov khoom ntawm cam khwb cia hlau, thiab ntxiv me me ntawm scandium rau txhuas tuaj yeem txhim kho nws lub zog thiab kub ua haujlwm. Hauv kev lag luam hluav taws xob, scandium tuaj yeem siv los ua ntau yam khoom siv semiconductor, xws li daim ntawv thov ntawm scandium sulfite hauv semiconductors tau nyiam nyob hauv tsev thiab txawv teb chaws, thiab scandium uas muaj ferrites muaj lub neej yav tom ntej hauv computer cores. Hauv kev lag luam tshuaj, cov tshuaj scandium yog siv los ua dehydrogenation thiab dehydration agents rau cawv los tsim ethylene thiab muaj txiaj ntsig catalysts los tsim cov tshuaj chlorine los ntawm khib nyiab hydrochloric acid. Hauv kev lag luam iav, iav tshwj xeeb uas muaj scandium tuaj yeem tsim tau. Hauv kev lag luam hluav taws xob lub teeb pom kev lag luam, scandium sodium teeb ua los ntawm scandium thiab sodium muaj qhov zoo ntawm kev ua haujlwm siab thiab zoo lub teeb xim.
