Wiilka iftiinka ka mid ah biraha dhif ah ee dhulka - scandium

Scandiumwaa curiye kiimiko ah oo leh astaanta curiyahaSciyo lambarka atomiga 21. Cunsurku waa bir kala-guur oo jilicsan, qalin-cad oo inta badan lagu qasogadolinium, erbiumiwm. Wax-soo-saarku aad buu u yar yahay, waxa ku jira qolofka dhulka waxa ku jira qiyaastii 0.0005%.

1. Qarsoodiga ahscandiumcuriye
barta dhalaalaysa eescandiumwaa 1541 ℃, barta karkaraya waa 2836 ℃, cufnaantana waa 2.985 g/cm³. Scandium waa bir khafiif ah, qalin-caddaan ah oo sidoo kale aad u falcelisa kiimiko ahaan waxayna la falgali kartaa biyo kulul si ay u dhaliyaan hydrogen. Sidaa darteed, iskaanka birta ah ee aad sawirka ku aragtaan waxa lagu xidhay dhalada waxaana lagu ilaaliyaa gaaska argon. Haddii kale, scandium-ku wuxuu si dhakhso ah u samayn doonaa lakab madow oo jaale ah ama cawl oksaydh wuxuuna lumin doonaa dhalaalkiisa birta ah.  https://www.xingluchemical.com/high-quality-rare-earth-scandium-metal-sc-metal-with-factory-price-products/  
2. Isticmaalka ugu muhiimsan ee scandium
Isticmaalka scandium (sida walaxda ugu muhiimsan ee shaqada, maaha doping) waxay ku urursan yihiin jihooyin aad u dhalaalaya, mana aha buunbuunin in loogu yeero wiilka iftiinka.
1). Scandium sodium lamp waxaa loo isticmaali karaa in lagu iftiimiyo kumanaan qoys. Tani waa isha iftiinka korontada ee birta ah: nalka waxaa ka buuxa sodium iodide iyo scandium iodide, iyo scandium iyo foil sodium ayaa lagu daray isku mar. Inta lagu jiro dareeraha korantada sare, ions scandium iyo ions sodium siday u kala horreeyaan waxay sii daayaan iftiin leh mawjadaha sii deynta sifada. Xadhkaha spectral ee soodiyamku waa laba shucaac huruud ah oo caan ah oo kala ah 589.0 iyo 589.6nm, halka xadhkaha spectral ee scandium ay yihiin taxane u dhow ultraviolet iyo iftiin buluug ah oo ka imanaya 361.3 ilaa 424.7nm. Sababtoo ah waxay yihiin midabyo dhammaystiran, midabka guud ee iftiinka la soo saaray waa iftiin cad. Waa si sax ah sababtoo ah nalka soodhiyamka ee Scandium wuxuu leeyahay sifooyinka waxtarka sare ee iftiinka, midabka iftiinka wanaagsan, badbaadinta tamarta, nolosha adeegga dheer iyo awoodda jabinta ceeryaamo xooggan oo si weyn loogu isticmaali karo kamaradaha telefishinka iyo barxadaha, garoomada, iyo iftiinka waddooyinka. waxaana la yidhaahdaa qarni saddexaad. il iftiin leh. Dalka Shiinaha, nalalka noocan ah ayaa si tartiib tartiib ah loogu xayeysiiyaa sidii tignoolajiyada cusub, laakiin wadamada horumaray qaarkood, laambada noocan ah ayaa si weyn loo isticmaali jiray horaantii 1980-yadii.
2). Unugyada photovoltaic-ka ee qoraxda ayaa soo ururin kara iftiinka dhulka ku firidhsan oo ay u beddelaan koronto dhaqaajisa bulshada aadanaha. Scandium waa birta xannibaadda ugu fiican ee birta-insulator-semiconductor silicon photovoltaic unugyo iyo unugyada qorraxda
3). Isha Gamma ray, hubkan sixirka ah ayaa iskiis u soo saari kara iftiin weyn, laakiin iftiinka noocan ah ma heli karo indhaheenna qaawan. Waa dareere tamar sare leh. Waxa aan inta badan ka soo saarno macdanta waa 45Sc, taas oo ah isotope kaliya ee dabiiciga ah ee scandium. Nucleus kasta oo 45Sc ah wuxuu leeyahay 21 protons iyo 24 neutrons. Haddii aan ku dhejino scandium reactor nukliyeer oo aan u oggolaanno inuu nuugo shucaaca neutron-ka, sida daanyeer la geliyo foornada alchemy ee Taishang Laojun muddo 7,749 maalmood ah, 46Sc oo leh hal neutron oo kale oo nukleus ah ayaa dhalan doona. 46Sc, isotope shucaac ah oo macmal ah, waxaa loo isticmaali karaa il gamma ray ama atom raadiyaha, waxaana sidoo kale loo isticmaali karaa daaweynta shucaaca ee burooyinka halista ah. Waxaa jira adeegsiyo aan la tirin karin sida yttrium-gallium-scandium garnet lasers, scandium fluoride galaas infrared optical fibers, iyo tuubooyinka rayiga ee scandium-dahaarka leh ee telefishinada. Waxay u muuqataa in scandium loo qoondeeyay inay noqoto mid dhalaalaya.
3. Xeryaha caadiga ah ee scandium    1). Terbium scandate (TbScO3) crystal - waxay leedahay shabag wanaagsan oo u dhigma qaab dhismeedka perovskite superconductors, waana wax aad u fiican oo ferroelectric khafiif ah oo ka samaysan substrate.
2).Aluminium scandium alloy- Marka hore, waa aluminium aluminium ah oo tayo sare leh. Waxaa jira dhowr siyaabood oo lagu hagaajin karo waxqabadka aluminium aluminium. Waxaa ka mid ah, microalloying iyo xoojinta iyo adkeynta waxay safka hore kaga jireen cilmi-baarista aluminium aluminium ee waxqabadka sare leh ee 20-kii sano ee la soo dhaafay. Dhismaha maraakiibta, hawada hawada Rajada codsiga ee qaybaha teknoolojiyadda sare sida warshadaha, gantaalada, iyo tamarta nukliyeerka ayaa aad u ballaaran.
3).Scandium oxide- Scandium oxide waxa ay leedahay sifooyin jidheed iyo kiimiko oo aad u wanaagsan, sidaa awgeed waxa ay leedahay codsiyo balaadhan oo dhanka sayniska agabka ah. Marka hore, scandium oxide waxaa loo isticmaali karaa wax lagu daro walxaha dhoobada ah, taas oo hagaajin karta adkaanta, xoogga iyo xirashada caabbinta dhoobada, taas oo ka dhigaysa kuwo sii waaraya. Intaa waxaa dheer, scandium oxide sidoo kale waxaa loo isticmaali karaa in lagu diyaariyo qalabka sare ee heerkulka sare. Qalabkani waxa ay muujinayaan korantada wanaagsan ee heerkulka hooseeya waxayna leeyihiin awood codsi oo weyn.
