Muna 1879, Sweden Chemistry profesa LF Nilson (1840-1899) uye Pt Clevel (1840-1905) akawana chinhu chitsva chingangoita manyama gadolinite uye dema risingawanzo goridhe ore panguva imwe chete. Vakatumidza chinhu ichi "Scandium"
Kuenzaniswa nezvinhu zveLannades, Scandium ine idiki diki ionic radius uye alkalinity ye hydroxide hainawo isina kusimba. Naizvozvo, apo scandium uye zvinhu zvisingawanzo kusanganiswa pamwe chete, vanobatwa neAmmonia (kana kuti vakanyanya kudiwa Alkali), uye scandium ichadonha kutanga. Naizvozvo, inogona kuparadzaniswa nyore nyore kubva pane zvisingawanzo kuitika pasi zvinhu ne "graded rumbiro" nzira. Iyo imwe nzira ndeye kushandisa iyo yekupaza kwekutora kweNitrate yekuparadzaniswa, nekuti Scandium nitrate ndiyo iri nyore kupatsanura, kuitira kuti uwane chinangwa chekuparadzaniswa.
Scandium yesimbi inogona kuwanikwa nemagetsi. Munguva yekunatswa kweScrondium,Scl3, KCL, naLicl vari kunyungudutswa, uye vakaumbwa zinc vanoshandiswa secathode yeElectrolysis kuti vaone scandium pane zinc elelelerode. Zvadaro, zinc inozovererwa kuti awane scandium yesimbi. Uye zvakare, zviri nyore kupora scandium kana uchigadzirisa ore kuburitsa uranium, trorium, uye lanthanide zvinhu. Kudzoreredzwa kwakazara kwekutevera Scandium kubva kuTungsten uye Tin Mines zvakare ndiyo yakakosha sosi ye scandium. Scandium inonyanya kuve mumamiriro ezvinhu akaenzana mumakomputa uye ari nyore oxidized kuneSC2O3Mumhepo, kurasikirwa nesimbi yesimbi uye kutendeuka kuita grey grey. Scanduum inogona kuita nemvura inopisa kuti isunungure hydrogen uye inokanganisa acids, ichiita kuti ive yakasimba yekuderedza mumiririri. Iyo oxides uye hydroxides ye scandium ichingoratidza chete alkalinity, asi munyu wawo ash haakwanisi kuve hydrolyzed. Iyo chloride ye scandium ndeyechena chena iyo inochema nyore mumvura uye inogona kukunzwa mumhepo. Mainini mainonyorera ndezvekutevera.
. Semuenzaniso, kuwedzera shoma scandium kune yakanyungudutswa simbi inogona kuvandudza zvakanyanya zvivakwa zvekukanda simbi, uchiwedzera scandium kuAluminium inogona kugadzirisa simba rayo uye kupisa kupisa.
. Ferrites ane Scandium zvakare ane kuvimbisa mashandisirwo emakomputa emagariro emakomputa.
.
(4) Muindasitiri yegirazi, girazi rakakosha rine scandium rinogona kugadzirwa.
.
Scandium iripo muchimiro che15Sc muchisikirwo, uye kune zvakare 9 radioactive isotopes ye scandium, iyo 40-44Sc uye 16-49SC. Pakati pavo, 46Sc akashandiswa se tracer mumakemikari, metallurgical, uye Ocanographic minda. Mukurapa, kunewo mufundo zvakare kunze kwenyika uchishandisa 46Sc kubata cancer.
