Scandiumchinhu chemakemikari chine chiratidzo chechinhuScuye nhamba yeatomu 21. The element isimbi yakapfava, chena-chena inoshandura iyo inowanzosanganiswa nayogadolinium, erbium, etc. Kubuda kwacho kuduku zvikuru, uye zviri mukati mepasi pevhu zvinenge 0.0005%.
1. Chakavanzika chescandiumelement Iyo yekunyungudika kwescandiumiri 1541 ℃, panofashaira i2836 ℃, uye density i2.985 g/cm³. Scandium isimbi yakareruka, sirivheri-chena iyo zvakare inoshanda zvakanyanya mumakemikari uye inogona kuita nemvura inopisa kugadzira haidrojeni. Naizvozvo, iyo simbi scandium yaunoona pamufananidzo yakavharirwa mubhodhoro uye yakachengetedzwa neargon gasi. Zvikasadaro, iyo scandium inokurumidza kuumba yakasviba yero kana grey oxide layer uye kurasikirwa neinopenya simbi inopenya.
2. Kushandiswa kukuru kwe scandium Kushandiswa kwe scandium (sechinhu chikuru chekushanda, kwete chedoping) chakaiswa mumigwagwa yakajeka, uye haisi kuwedzeredza kuidana kuti mwanakomana wechiedza. 1). Scandium sodium rambi inogona kushandiswa kuunza chiedza kuzviuru zvedzimba. Iyi isimbi halide yemagetsi mwenje sosi: iyo girobhu izere ne sodium iodide uye scandium iodide, uye scandium uye sodium foil inowedzerwa panguva imwe chete. Munguva yekubuda kwe-high-voltage, scandium ions uye sodium ions zvakateerana zvinoburitsa mwenje nehunhu hwadzo hwekuburitsa wavelengths. Mitsetse yesodium ine mbiri yakakurumbira yero rays pa 589.0 uye 589.6nm, nepo spectral mitsetse ye scandium iri nhevedzano yepedyo-ultraviolet uye yebhuruu chiedza emissions kubva 361.3 kusvika 424.7nm. Nekuti iwo anoenderana mavara, iyo yakazara mwenje ruvara inogadzirwa ichena mwenje. Ndizvo chaizvo nekuti mwenje wesodium we scandium une hunhu hwekupenya kwakanyanya, kunaka kwemavara echiedza, kuchengetedza simba, hupenyu hurefu hwesevhisi uye kugona kwakasimba kwekupwanya mhute iyo inogona kushandiswa zvakanyanya mumakamera eterevhizheni uye masikweya, nhandare, uye mwenje wemugwagwa, uye unonzi chizvarwa chechitatu. light source. MuChina, rudzi urwu rwemwenje runosimudzirwa zvishoma nezvishoma se tekinoroji nyowani, asi mune dzimwe nyika dzakabudirira, rudzi urwu rwemwenje rwakashandiswa zvakanyanya sekutanga kwema1980. 2). Solar photovoltaic masero anogona kuunganidza chiedza chakapararira pasi uye kuchishandura kuva magetsi anotyaira nzanga yevanhu. Scandium ndiyo yakanakisa chipingamupinyi simbi musimbi-insulator-semiconductor silicon photovoltaic masero uye solar masero. 3). Gamma ray sosi, ichi chombo chemashiripiti chinogona kuburitsa chiedza chikuru chega, asi rudzi urwu rwechiedza harugone kugamuchirwa nemeso edu asina kupfeka. Iyo yakakwirira-simba photon inoyerera. Zvatinowanzo bvisa kubva kumaminerari ndeye 45Sc, inova ndiyo yega isotope yechisikigo ye scandium. Imwe neimwe 45Sc nucleus ine 21 protons uye makumi maviri nemana manyuturoni. Kana tikaisa scandium mureactor yenyukireya toirega ichitora neutron radiation, sekuisa tsoko muvira reTaishang Laojun's alchemy for 7,749 days, 46Sc ine imwe neutron munucleus inozvarwa. 46Sc, an artificial radioactive isotope, inogona kushandiswa segamma ray sosi kana tracer atomu, uye inogona zvakare kushandiswa kurapa radiotherapy yemamota akaipa. Pane zvisingaverengeki zvinoshandiswa zvakadai seyttrium-gallium-scandium garnet lasers, scandium fluoride girazi infrared optical fibers, uye scandium-coated cathode ray chubhu mumaterevhizheni. Zvinoita sekuti scandium inotarisirwa kuve yakajeka. 3. Zvakajairwa makomisheni e scandium 1). Terbium scandate (TbScO3) crystal - ine yakanaka lattice inoenderana ne perovskite chimiro superconductors, uye yakanakisa ferroelectric nhete firimu substrate zvinhu.
2).Aluminium scandium alloy- Chekutanga, ndeye yakakwirira-inoshanda aluminium alloy. Pane nzira dzinoverengeka dzekuvandudza mashandiro ealuminium alloys. Pakati pavo, microalloying uye kusimbisa uye kuomesa kwave kuri mberi kwepamusoro-kushanda kwealuminium alloy tsvakurudzo mumakore makumi maviri apfuura. Mukuvaka ngarava, aerospace Matarisiro ekushandisa muzvikamu zvepamusoro-tekinoroji zvakaita seindasitiri, zvombo zvemaroketi, uye simba renyukireya zvakapamhama. 3).Scandium oxide- Scandium oxide ine yakanakisa yemuviri uye kemikari zvivakwa, saka ine huwandu hwakasiyana hwekushandisa mumunda wezvekushandisa sainzi. Kutanga, scandium oxide inogona kushandiswa sechinhu chinowedzera mu ceramic zvinhu, izvo zvinogona kuvandudza kuoma, simba uye kupfeka kupikisa kwekeramic, zvichiita kuti zvive zvakasimba. Mukuwedzera, scandium oxide inogonawo kushandiswa kugadzirira yakakwirira-tembiricha superconductor zvinhu. Zvishandiso izvi zvinoratidzira yakanaka conductivity yemagetsi pane yakaderera tembiricha uye zvine hukuru hwekushandisa. Nguva yekutumira: Nov-01-2024
