scandium oxide 99.99%

Scandium oxide (Sc2O3) waa mid ka mid ah alaabada ugu muhiimsan ee scandium.Sifooyinkeeda jidheed iyo kiimikaadba waxay la mid yihiin kuwa dhulka oksaydhyada naadirka ah (sida La2O3, Y2O3 iyo Lu2O3, iwm.), sidaa awgeed hababka wax-soo-saarka ee loo isticmaalo wax-soo-saarka aad bay isugu mid yihiin.Sc2O3 waxay soo saari kartaa birta Scandium (sc), cusbo kala duwan (ScCl3, ScF3, ScI3, Sc2 (C2O4) 3, iwm.) iyo Alloys scandium kala duwan (Al-Sc, Al-Zr-Sc series).Alaabooyinka scandium waxay leeyihiin qiimo farsamo oo wax ku ool ah iyo saameyn dhaqaale oo wanaagsan.Sc2O3 ayaa si weyn loogu isticmaalay aluminium aluminium, isha iftiinka korontada, laser, kicinta, firfircoonida, ceramics, aerospace iyo wixii la mid ah sababtoo ah sifooyinka.Waqtigan xaadirka ah, heerka codsiga ee Sc2O3 ee beeraha daawaha, ilaha iftiinka korontada, kicinta, firfircoonida iyo ceramics ee Shiinaha iyo adduunka ayaa lagu sifeeyaa mar dambe.

(1) Codsiga daawaha

daawaha scandium

Waqtigan xaadirka ah, daawaynta Al-Sc ee ka samaysan Sc iyo Al waxay leedahay faa'iidooyinka cufnaanta hoose (SC = 3.0g / cm3, Al = 2.7g / cm3, xoog sare, qallafsanaan sare, caag wanaagsan, caabbinta daxalka xooggan iyo xasilloonida kuleylka, iwm. Sidaa darteed, si fiican ayaa loo dabaqay qaybaha qaab dhismeedka gantaalada, hawada sare, duulista, baabuurta iyo maraakiibta, waxaana si tartiib tartiib ah loogu soo jeestay isticmaalka rayidka, sida gacanta qalabka ciyaaraha (Xeegada iyo baseball) Waxay leedahay sifooyinka xoogga sare. , qallafsanaan sare iyo miisaan fudud, waana qiimo wax ku ool ah oo weyn.

Scandium inta badan waxay ka ciyaartaa doorka wax ka beddelka iyo sifaynta hadhuudhka ee daawaha, taas oo horseedaysa samaynta nooc cusub oo Al3Sc ah oo leh sifooyin aad u wanaagsan.Al-Sc alloy waxa ay samaysay taxane taxane ah, tusaale ahaan, Ruushku waxa uu gaadhay 17 nooc oo Al-Sc ah, sidoo kale Shiinuhu waxa uu leeyahay dhawr Alloy (sida Al-Mg-Sc-Zr iyo Al-Zn-Mg-Sc). alloy).Sifooyinka noocan oo kale ah laguma bedeli karo qalab kale, sidaas darteed marka laga eego dhinaca horumarinta, horumarinta codsigeeda iyo suurtogalnimada ayaa ah mid weyn, waxaana la filayaa inay noqoto codsi weyn mustaqbalka.Tusaale ahaan, Ruushku waxa uu leeyahay wax soo saar warshadaysan, waxana uu si degdeg ah u horumariyey qaybaha qaab-dhismeedka iftiinka, Shiinuhuna waxa uu dardargelinayaa cilmi-baadhistiisa iyo codsigiisa, gaar ahaan hawada iyo duulista.

isticmaalka scandium oxide

Sc2O3 saafi ah ayaa loo beddelay ScI3, ka dibna loo sameeyay jiil saddexaad oo cusub oo korantada ah oo leh NaI, kaas oo lagu farsameeyay nalka Scandium-sodium halogen ee nalka (qiyaastii 0.1mg ~ 10mg of Sc2O3≥99% walxo ayaa loo adeegsaday laambad kasta Hoosta ficilka tamarta sare, xariiqda spectral scandium waa buluug iyo xariiqda soodhiyamku waa jaale, labada midabba waxay la shaqeeyaan midba midka kale si ay u soo saaraan iftiin u dhow iftiinka qorraxda. badbaadinta tamarta, cimri dheer iyo awoodda jabinta ceeryaamo xooggan.

isticmaalka scandium oxide2

Gadolinium gallium scandium garnet (GGSG) waxaa lagu diyaarin karaa iyadoo lagu darayo Sc2O3≥ 99.9% GGG saafi ah, ka koobankeeduna waa nooca Gd3Sc2Ga3O12.Awoodda sii daynta ee jiilka saddexaad ee leysarka ka samaysan ayaa 3.0 jeer ka sarreeya kan leysarka leh mugga isku midka ah, kaas oo gaadhay qalab aad u sarreeya oo leysarka yar-yar, wuxuu kordhiyey awoodda wax-soo-saarka ee oscillation laser wuxuuna wanaajiyey waxqabadka laser-ka. .Marka la diyaarinayo hal crystal, Kharash kasta waa 3kg ~ 5kg, oo ku saabsan 1.0kg oo alaabta ceeriin leh Sc2O3≥99.9% lagu daray.Waqtigan xaadirka ah, nooca laser-ka ah ayaa si weyn loogu isticmaalaa tignoolajiyada militariga, waxaana sidoo kale si tartiib tartiib ah loogu riixaa warshadaha rayidka ah.Marka la eego dhinaca horumarka, waxa ay leedahay awood weyn oo dhanka militariga iyo isticmaalka rayidka mustaqbalka.

3. isticmaalka scandium oxide

Sc2O3 saafi ah waxaa loo isticmaali karaa sida kicinta cathode oxidation ee qoriga elektarooniga ah ee tuubada sawirka TV-ga midab leh oo leh saameyn wanaagsan.Ku buufin lakabka Ba, Sr iyo Ca oxide oo leh dhumuc dhan hal milimitir dushii cathode ee tuubada midabka, ka dibna ku kala firdhi lakabka Sc2O3 oo leh dhumuc dhan 0.1 millimitir.Katoodhka lakabka oksaydhka, Mg iyo Sr waxay la falgalaan Ba, taas oo kor u qaadaysa yaraynta Ba, iyo electrons-ka la sii daayo ayaa aad u firfircoon, oo bixiya electrons waaweyn oo hadda jira, taas oo ka dhigaysa fosfoorka iftiinka iftiinka. Marka la barbardhigo cathode aan lahayn daboolka Sc2O3 , waxay kordhin kartaa cufnaanta hadda 4 jeer, waxay ka dhigi kartaa sawirka TV-ga mid cad oo sii dheereynaya nolosha cathode 3 jeer.Qadarka Sc2O3 ee loo isticmaalo 21-inch kasta oo kobcaya cathode waa 0.1mg Waqtigan xaadirka ah, cathode-kan waxaa laga isticmaalay qaar ka mid ah wadamada aduunka, sida Japan, taas oo hagaajin karta tartanka suuqa iyo kor u qaadida iibinta qalabka TV-ga.
