Muuqaalka: Birta cawlan ee qalinka ah, isbuunyo, irbad qaabaysan, dhalaal cad oo bir ah, waa la gooyn karaa iyadoo loo eegayo shuruudaha macaamiisha
Astaamaha Jirka: Alaabta waa cad cad oo qalin ah, badiyaa waxay u qaabaysan tahay blocks crystalline distilled (jidhka oo kale) ee birta ah.Xirmooyinka, isbuunyada isbuunyada, ama muraayadaha waxay sidoo kale noqon karaan qaab shuban qaabeysan, oo leh meel nadiif ah. Si sahlan oo lagu milmo biyaha, waxay kaga falcelin karaan biyo kulul, waxayna si fudud u madoobanayaan hawada.
Codsiga:
Birta Scandiumwaxaa lagu dabaqaa daahan indhaha, kicinta, dhoobada elektarooniga ah iyo warshadaha laysarka.Codsiga ugu weyn ee Scandium miisaan ahaan wuxuu ku jiraa aluminium-Scandium alloys ee qaybaha warshadaha hawada yar yar.Qaar ka mid ah qalabka ciyaaraha, kuwaas oo ku tiirsan qalabka waxqabadka sare, ayaa lagu sameeyay Scandium-Aluminium alloys.Ka shaqeeya isku dhafka gobolka adag ee kooxo aan caadi ahayn, Sc19Br28Z4, (Z=Mn, Fe, Ru ama Os).Kooxahani waxay xiiseeyaan qaab-dhismeedkooda iyo sifooyinka birlabeedka.Waxa kale oo laga codsadaa in la sameeyo aluminium super. biraha Scandium waxaa loo isticmaalaa in qalabka Alloys-farsamada, ilaha iftiinka korontada, warshadaha unugyada shidaalka, warshadaha tamarta nukliyeerka, iyo warshadaha military Birta Scandium waxaa si weyn loo isticmaalaa in hawada, warshadaha elektarooniga ah, nalka, catalysis, nuclear. teknoolajiyada, tignoolajiyada heer sare ah, iyo goobo kale.
