Vim yog lub cim xeeb ntawm lub cev ntawm Sc2o3Scandium oxide, lawv tau ua tiav cov ntaub ntawv thov zoo hauv ntau cov thev naus laus zis thiab cov haujlwm lag luam txij li xyoo 1980s. Daim ntawv thov cov ntawv thov tam sim no ntawm Sc2o3 nyob rau hauv lub teb ntawm alloys, catalysts, cov kev ua kom zoo, thiab ib puag ncig hauv ntiaj teb no.
Daim ntawv thov nyob rau hauv alloys
Tam sim no, scandium oxide alloy (al SC) ua los ntawm kev ceev nrawm (SC yog 3. { Yog li ntawd, nws tau siv dav hauv cov qauv txheej txheem xws li Missiles, xws li lub zog ntawm cov neeg ntaus pob, thiab cov pob hluav taws xob, thiab lub teeb yuag, thiab yog qhov muaj txiaj ntsig ntawm tes.
Scandium tsuas yog ua lub luag haujlwm hauv kev hloov kho thiab kho cov nplej hauv cov theem ntawm AL3SC thiab nthuav tawm cov yam ntxwv zoo tshaj plaws ntawm Al3Sc thiab nthuav tawm cov yam ntxwv zoo tshaj plaws ntawm Al3Sc thiab nthuav tawm cov yam ntxwv zoo tshaj plaws ntawm alloys Al sur alloys tau tsim cov series ntawm alloy series, xws li 17 al sur series hauv Lavxias (xws li al mg mg mg sc alloys). Cov yam ntxwv ntawm hom ntawm no tsis tuaj yeem hloov los ntawm lwm cov ntaub ntawv, yog li los ntawm kev txhim kho kev loj hlob, nws yuav tsum tau ua ib qho kev thov loj, thiab nws yuav tsum tau ua ib qho kev thov loj heev rau yav tom ntej. Yog hais tias Russia tau muaj kev tsim khoom thiab tsim kho sai rau kev tshawb fawb me me, Tuam Tshoj kuj yog nyob rau hauv lub teb ntawm Aerospace thiab aviation nrog cov kev cia siab zoo tshaj plaws.
Daim Ntawv Thov Uas Siv Hluav Taws Xob Lub Teeb Hluav Taws Xob Tshiab
Ib qho khoom siv thib peb tshiab thib peb lub teeb hluav taws xob tshiab yog tsim los ntawm kev hloov pauv ntshiab scion3 thiab tom qab ntawd ua rau ecogen luj Nyob rau hauv lub siab voltage, lub scandium spletral kab tshwm sim xiav thiab ob lub teeb pom kev zoo, thiab ob lub teeb pom kev zoo, txuag lub zog, thiab muaj zog deardging zog.
Cov ntawv thov hauv Laser cov ntaub ntawv
Ntxiv cov ntshiab sc2o3 ntau dua lossis sib npaug rau 99.9% rau Gadolinium gallium gallet (GGSG), uas yog nyob rau hauv daim ntawv ntawm GD3Sc2GA3O12. The emission power of the third-generation laser made from it is 3.{{10}} times higher than that of lasers of the same volume, achieving high-power and miniaturized laser devices, increasing laser oscillation output power, and improving laser performance. Thaum npaj ib qho muaju nkaus xwb, txhua qhov cub tawg yog 3kg rau 5kg, thiab ntxiv rau sc2o3 ntau dua lossis sib npaug ntawm 99.9% raw khoom yog hais txog 1.0kg. Tam sim no, daim ntawv thov ntawm hom laser no hauv kev ua tub rog thev naus laus zis yog ua kom dav, thiab nws yog maj mam raug thawb mus rau kev lag luam pej xeem. Los ntawm kev nthuav dav, muaj peev xwm zoo rau kev ua tub rog thiab pej xeem siv yav tom ntej.
Cov ntawv thov hauv cov ntaub ntawv hluav taws xob
Ntshiab Sc2o3 tuaj yeem siv ua Oxidizing Cathode activator rau cov xim TV Cathode Cov phom hluav taws xob hluav taws xob, nrog cov txiaj ntsig zoo. Txau ib tug txiv millimeter tuab txheej ntawm BA, sr, CA Oxide ntawm cov xim raj, thiab tom qab ntawd tawg {}}. 1}}. 1}}. 1}}. 1}}. 1}}. 1}}. 1}}. 1}}. 1 Nyob rau sab saum toj. Nyob rau hauv lub Cathohode ntawm oxide txheej ntawm mg, sr thiab ba txhawb nqa cov hluav taws xob hluav taws xob thiab emitting ntau tam sim no, ua rau lub teeb ci rau emit. Piv nrog rau cathode yam tsis muaj sc2o3 txheej, nws tuaj yeem nce qhov ceev tam sim no los ntawm 4 zaug, ua kom lub tv daim duab ntshiab, thiab nce cov Cathode lub neej los ntawm 3 zaug. Txhua 21 nti Cathode siv 0. 1mg ntawm sc2o3. Tam sim no, cathode no siv nyob rau hauv qee lub tebchaws thoob ntiaj teb, xws li Nyij Pooj, uas tuaj yeem txhim kho kev ua lag luam sib tw thiab txhawb kev muag khoom TV.
Tom qab xyoo ntawm kev tshawb fawb thiabScandium oxideXyaum hauv cov tshuab ntau lawm thiab cov cuab yeej siv tam sim no, tseem muaj ntau txoj hauv kev rau kev rho tawm sc2o3 los ntawm scandium muaj cov khoom siv raw:
Cov kev rho tawm.
Nws yog dav siv nyob rau hauv kev tsim khoom nyob rau hauv ntau lawm thiab muaj cov yam ntxwv ntawm cov zis siab, zoo zoo, kev rov qab siab dua, thiab kev ua haujlwm tsis tu ncua hauv kev tsim khoom.
② ion txauv qauv.
Nws tseem siv nyob rau hauv ntau lawm. Nws muaj cov yam ntxwv ntawm kev txo qis, siab huv, qis tawm los, nqi ntau, thiab ntau lawm ntau lawm.
③ Extraction Resin chromatogy txoj kev.
Nws muaj cov yam ntxwv ntawm luv luv voj voog, siab huv, siab tawm los, thiab tus nqi tsawg.
④ Kua membrane extraction txoj kev.
Nws yog qhov kev sib cais tshiab sib cais thev naus laus zis uas sib xyaw ua ke nrog cov kua dej ua kua. Tab sis tam sim no tsis muaj kev xyaum ntau lawm. Qee tus neeg ib zaug siv cov kua emulsion ua kua rau enrick
Los ntawm lub xyoo ntawm kev rho tawm sc2o3 hauv peb lub tebchaws, nws tuaj yeem pom tau tias yuav luag thawj ob txoj kev ua tiav
Technology (Extraction txoj kev thiab ion sib pauv qauv) yog qhov tseem ceeb.
