Scandiumyog cov tshuaj lom neeg nrog lub cim tseem ceebScthiab atomic naj npawb 21. Lub ntsiab lus yog qhov muag muag muag, cov nyiaj dawb uas feem ntau sib xyaw nroggadolinium, hoob laug, etc. Cov zis yog qhov tsawg heev, thiab nws cov ntsiab lus hauv ntiaj teb crust yog li 0.0005%.
1. Lub yeej ntawmscandiumlub ntsiab Lub ntsiab lus melting ntawmscandiumyog 1541 ℃, qhov cub npau npau yog 2836 ℃, thiab qhov ceev yog 2.985 g / cm³. Scandium yog lub teeb, cov nyiaj-hlau dawb uas tseem yog cov tshuaj tiv thaiv zoo heev thiab tuaj yeem hnov mob nrog dej kub kom tsim kom muaj hydrogen. Yog li no, cov hlau scandium koj pom hauv daim duab yog muab ntim rau hauv lub raj mis thiab tiv thaiv nrog cov roj sib cav. Txwv tsis pub, cov scandium yuav ua rau sai sai rau xim daj lossis xim oxide thiab poob nws lub ntsej muag ci ntsa iab.
2. Lub ntsiab siv ntawm scandium Kev siv ntawm scandium (raws li cov khoom ua haujlwm tseem ceeb, tsis yog rau doping) muaj cov lus qhia ci ci heev, thiab nws tsis yog kev ua rau nws hu nws lub teeb. 1). Scandium sodium teeb tuaj yeem siv coj lub teeb mus rau ntau txhiab tsev neeg. Qhov no yog lub teeb hluav taws xob hlau hluav taws xob muaj lub teeb hluav taws xob Thaum lub sij hawm high-voltage tshem tawm, scandium ions thiab sodium ions feem teeb pom kev nrog lawv tus yam ntxwv emission emission. Lub ntsej muag hluav taws xob ntawm sodium yog ob lub npe nrov daj ntawm 589.0 thiab 589.6nm, thaum lub teeb pom kev zoo nkauj thiab xiav teeb emissions los ntawm 361.3 txog 424.7nm. Vim tias lawv tau ua cov xim zoo nkauj, lub teeb xim zuag qhia tag nrho tsim yog lub teeb dawb. Nws yog qhov tseeb vim tias lub teeb ci scandium teeb muaj cov yam ntxwv ntawm cov koob yees duab siab, lub zog zoo, thiab yog hu ua lub cim thib peb. Lub qhov teeb pom kev. Hauv Suav teb, hom teeb no tau nce qib tshiab, tab sis hauv qee lub tebchaws tsim tau, cov teeb tsim tawm dav dav tau siv thaum ntxov xyoo 1980s. 2). Solar phot photoHovoltic cov hlwb tuaj yeem sau lub teeb tawg ri niab rau hauv av thiab tig nws mus rau hauv hluav taws xob uas ua rau tib neeg lub zej zog. Scandium yog qhov zoo tshaj plaws barrier hlau nyob rau hauv hlau-insulator-saciconductor silicon photovoltaic thiab solar hlwb 3). Gamma Ray Windows, Qhov riam phom no tuaj yeem ua pov thawj lub teeb ci ci ntawm nws tus kheej, tab sis hom teeb tsis tuaj yeem tau txais los ntawm peb lub qhov muag liab qab. Nws yog lub zog hluav taws xob loj. Dab tsi peb feem ntau rho tawm los ntawm cov zaub mov yog 45sc, uas yog qhov tsuas yog ntuj Isotope ntawm scandium. Txhua txhua 45sc nucleus muaj 21 cov protons thiab 24 neutrons. Yog tias peb tso scandium nyob rau hauv ib tug nuclear reactor thiab cia nws nqus kev ua kom lub ntsej muag ib txwm muaj rau 7,749 hnub, 46sc nrog ib qho ntau neutron hauv lub nucleus yuav yug. 46SC, ib qho khoom siv hluav taws xob cuav, tuaj yeem siv ua gamma ray qhov chaw lossis tracer atom, thiab kuj tseem siv tau rau cov qog ua qog. Muaj ntau cov usourless used xws li yttrium-gallium ghaters gluoride optical iav infrarition iav infrarition Optical cov hlua hauv TV. Nws zoo nkaus li tias scandium yog destined yuav ci. 3, cov tebchaw ntawm scandium 1). Terbium Scandate (Tbsco3) Crystal - Muaj Lattice Zoo Tshaj Plaws nrog Perovskite Qauv Superconductors, thiab yog ib tug zoo ferroelectric nyias zaj duab xis ua cov khoom siv substrate
2).Aluminium scandium alloy- Ua ntej, nws yog qhov kev ua tau zoo aluminium alloy. Muaj ntau txoj hauv kev los txhim kho kev ua tau zoo ntawm txhuas alloys. Ntawm lawv, microalloying thiab tawv thiab tawv tau yog thawj zaug ntawm kev ua tau zoo aluminium agoy nyob rau hauv 20 xyoo dhau los. Hauv lub nkoj nkoj, aerospace daim ntawv thov kev cia siab hauv cov haujlwm siab xws li kev lag luam, pob zeb khib nyiab, thiab dav dav. 3).Scandium oxide- Scandium oxide muaj cov khoom siv lub cev thiab tshuaj zoo heev, yog li nws muaj ntau cov kev siv hauv cov ntaub ntawv tshawb fawb. Ua ntej, Scandium oxide tuaj yeem siv los ua cov khoom ntxiv hauv cov khoom sib txuas, uas tuaj yeem txhim kho lub hardness, lub zog thiab hnav tsis kam ntawm ceramics, ua rau lawv muaj ntau ruaj khov. Ib qho ntxiv, Scandium oxide kuj tseem siv tau los npaj high-kub superconductor cov ntaub ntawv. Cov khoom siv no nthuav qhia qhov hluav taws xob zoo ntawm cov kub tsawg thiab muaj peev xwm zoo kawg.
