Ikhentiyamuyinto yamakhemikhali ngophawu lwe-elementScne-atomic inombolo 21. Into yensimbi ethambile, emhlophe yesiliva evame ukuxutshwaigadiki, umphetho, njll. Ukukhishwa kuncane kakhulu, futhi okuqukethwe kwalo ku-crust yomhlaba cishe ngo-0.0005%.
1. Imfihlakalo yeikhentiyamuisithako semvelo Iphuzu lokuncibilika leikhentiyamungu-1541 ℃, iphuzu elibilayo lingu-2836 ℃, futhi ubuntu bungu-2.985 g / cm³. I-Scandium iyinsimbi elula, emhlophe yesiliva esebenza futhi esebenza kakhulu ngamakhemikhali futhi ingasabela ngamanzi ashisayo ukukhiqiza i-hydrogen. Ngakho-ke, i-scandium yensimbi oyibona esithombeni ibhalwe ebhodleleni futhi ivikelwe ngegesi ye-argon. Ngaphandle kwalokho, i-Scandium izokwakha ngokushesha ungqimba oluphuzi olumnyama noma olumpunga oxide ongifisayo bese ulahlekelwa yi-shiny metallic luster.
2. Ukusetshenziswa okuyinhloko kweScandium Ukusetshenziswa kweScandium (njengento esemqoka esebenzayo, hhayi i-doping) kugxile ezinkomba ezikhanyayo kakhulu, futhi akulona yihaba ukubiza ngokuthi indodana yokukhanya. 1). Isibani seScandium Sodium singasetshenziswa ukuletha ukukhanya ezinkulungwaneni zamakhaya. Lona yi-Metal Halide Electric Light Source Ekagesi: Isibani sigcwele i-sodium iodide ne-scandium iodide, futhi i-scandium ne-sodium foil ingezwa ngasikhathi sinye. Ngesikhathi sokukhishwa kwamandla aphezulu, ama-scandium ion nama-sodium ion ngokulandelana akhanya ngokukhanya ngamagagasi abo okuphuma. Imigqa yokubuka i-sodium ye-sodium iyimisebe emibili ephuzi ephuzi ngo-589.0 no-589.6nm, ngenkathi imigqa yokubuka i-scandium inguchungechunge lokukhanya okukhanyayo okuphezulu nokukhanya okuluhlaza okwesibhakabhaka kusuka ku-361.3 kuya ku-424.7nm. Ngoba zinemibala ehambisanayo, kukhiqizwa umbala okhanyayo ophelele ukukhanya okumhlophe. Yingobuqiniso ngoba isibani seScandium Sodium sinezimpawu zokusebenza kahle okukhanyayo, umbala omuhle wokukhanya, ukulondolozwa kwamandla, impilo yesevisi ebanzi kanye nekhono lokuqhekeka elinamandla kangangokuba lingasetshenziswa kabanzi kumakhamera wethelevishini nasezigcawini, kanye nokukhanyisa umgwaqo, futhi kubizwa ngokuthi isizukulwane sesithathu. umthombo okhanyayo. EChina, lolu hlobo lwesibani lunyuswa kancane kancane njengobuchwepheshe obusha, kodwa kwamanye amazwe athuthukile, lolu hlobo lwesibani lusetshenziswe kabanzi ekuqaleni kweminyaka yo-1980. 2). Amaseli we-Solar Photovoltaic angaqoqa ukukhanya okusakazeke emhlabathini futhi akuguqule ngogesi olungisa umphakathi wesintu. I-Scandium iyinsimbi engcono kakhulu yesithiyo e-Metal-insulator-semiconductor silicon photovoltaic cell namaseli elanga 3). Umthombo we-Gamma Ray, lesi sikhali somlingo singakhipha ukukhanya okukhulu sodwa, kepha lolu hlobo lokukhanya alunakwamukelwa ngamehlo ethu anqunu. Kungukugeleza kwe-Photon Photon ephezulu. Esivame ukukhipha amaminerali yi-45sc, okuyi-isotope yemvelo kuphela yeScandium. I-Nucleus ngayinye ye-45sc inezimpawu ezingama-21 nama-neutrons angama-24. Uma sibeka iScandium e-reactium yenuzi futhi siyivumele imisebe ye-neutron, njengokubeka inkawu ngesitha somshini kaTaishang Laojun izinsuku ezingama-7 749, 46SC nge-neutron eyodwa e-nucleus izozalwa. I-46SC, I-Isotope ye-Radioactive Enemba, ingasetshenziswa njengomthombo we-gamma ray noma i-athomu ye-tracer, futhi nayo ingasetshenziselwa i-radigItherapy yama-tumors amabi. Kunokusetshenziswa okuningana okufana ne-ytttrium-gallium-scandium garnet lasers, i-scandium fluoride ingilazi ye-infrared infrared fibers, kanye namashubhu we-cathode ahlanganisiwe we-scandium kuma-telvion amasethi wethelevishini. Kubukeka sengathi iScandium yenzelwe ukuba igqamile. I-3, amakhompiyutha ajwayelekile weScandium 1). I-Terbium Scandate (TBSCO3) I-Crystal - ine-lattice enhle ehambelana ne-Perovskite sakhiwo superconductors, futhi iyinto enhle kakhulu ye-Ferroelectric mncane yefilimu
2).I-Aluminium Scandium Alloy- Okokuqala, kuyinto esebenza kahle ye-aluminium alloy. Kunezindlela eziningana zokwenza ngcono ukusebenza kwama-aluminium alloys. Phakathi kwazo, ama-microallooling kanye nokuqinisa futhi okuqinile kube phambili kokucwaninga okuphezulu kwe-aluminium Alloy eminyakeni engama-20 edlule. E-SHICDUIDIDING, AEROSPACE amathemba wohlelo lokusebenza kwimikhakha ephezulu yobuchwepheshe efana nemboni, imicibisholo ye-rocket kanye namandla enuzi abanzi kakhulu. 3).Scandium oxide- I-Scandium Oxide inezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali, ngakho-ke inezinhlobonhlobo zezicelo emkhakheni wesayensi yezinto zokwakha. Okokuqala, i-Scandium Oxide ingasetshenziswa njengesengezo sezinto zokwenziwa kwe-ceramic, ezingathuthukisa ubulukhuni, amandla nokuvimbela ukumelana kwama-ceramics, kubenza bahlala isikhathi eside. Ngaphezu kwalokho, i-scandium oxide nayo ingasetshenziswa ukulungiselela izinto eziphakeme zokushisa superconductor. Lezi zinto zokwakha zibonisa ukuqina kukagesi okuhle emazingeni okushisa aphansi futhi kube namandla amakhulu okufaka isicelo. Isikhathi sePosi: Nov-01-2024
