Kugwiritsa ntchito scandium oxide Sc2O3 ufa

Kugwiritsa ntchito scandium oxide

Njira yamankhwala ya scandium oxide ndi Sc2O3. Katundu: Cholimba choyera. Ndi ma kiyubiki dongosolo la osowa lapansi sesquioxide. Kachulukidwe 3.864. Malo osungunuka 2403 ℃ 20 ℃. Insoluble m'madzi, sungunuka mu asidi otentha. Amakonzedwa ndi kuwonongeka kwa mchere wa scandium. Itha kugwiritsidwa ntchito ngati zinthu za evaporation za zokutira za semiconductor. Pangani laser yolimba yokhala ndi kutalika kwa kutalika, kutanthauzira kwakukulu kwa mfuti yamagetsi ya TV, nyali yachitsulo ya halide, ndi zina zambiri.

Scandium oxide (Sc2O3) ndi imodzi mwazinthu zofunika kwambiri za scandium. Maonekedwe ake akuthupi ndi mankhwala amafanana ndi ma oxides osowa padziko lapansi (monga La2O3,Y2O3 ndi Lu2O3, etc.), kotero njira zopangira zomwe zimagwiritsidwa ntchito popanga ndizofanana kwambiri. Sc2O3 akhoza kupanga zitsulo Scandium (sc), mchere zosiyanasiyana (ScCl3, ScF3, ScI3, Sc2 (C2O4) 3, etc.) ndi kaloti zosiyanasiyana scandium (Al-Sc, Al-Zr-Sc mndandanda). Izi mankhwala scandium ndi zothandiza luso luso ndi wabwino effect.Sc2O3 wakhala ankagwiritsa ntchito zitsulo zotayidwa aloyi, magetsi kuwala gwero, laser, chothandizira, activator, zoumba, Azamlengalenga ndi zina zotero chifukwa cha makhalidwe ake. Pakalipano, ntchito ya Sc2O3 m'magawo a aloyi, magetsi opangira magetsi, chothandizira, activator ndi zoumba ku China ndi dziko lapansi zikufotokozedwa pambuyo pake.

(1) kugwiritsa ntchito aloyi

Pakalipano, aloyi ya Al-Sc yopangidwa ndi Sc ndi Al ili ndi ubwino wocheperako (SC = 3.0g/cm3, Al = 2.7g/cm3, mphamvu yayikulu, kuuma kwakukulu, pulasitiki yabwino, kukana kwa dzimbiri komanso kukhazikika kwamafuta, etc. Choncho, wakhala bwino ntchito mu zigawo structural wa mivi, ndege, ndege, magalimoto ndi zombo, ndipo pang'onopang'ono anatembenukira kwa ntchito wamba, monga amangokhalira zipangizo masewera (hockey ndi baseball) Iwo ali ndi makhalidwe a mphamvu mkulu. , yolimba kwambiri komanso yopepuka, ndipo ndi yamtengo wapatali kwambiri.

Scandium makamaka imagwira ntchito yosintha ndi kukonza mbewu mu aloyi, zomwe zimapangitsa kuti pakhale mtundu watsopano wa Al3Sc wokhala ndi katundu wabwino kwambiri. Al-Sc alloy apanga mndandanda wa aloyi angapo, mwachitsanzo, Russia yafika mitundu 17 ya Al-Sc, ndipo China ilinso ndi ma aloyi angapo (monga Al-Mg-Sc-Zr ndi Al-Zn-Mg-Sc. aloyi). Makhalidwe amtundu uwu wa aloyi sangasinthidwe ndi zida zina, kotero kuchokera kumalingaliro a chitukuko, chitukuko ndi kuthekera kwake ndizopambana, ndipo zikuyembekezeka kukhala ntchito yayikulu mtsogolomo. Mwachitsanzo, dziko la Russia lili ndi ntchito zopanga mafakitale ndipo likukula mwachangu kuti lizipanga magawo opepuka, ndipo China ikufulumizitsa kafukufuku wake ndikugwiritsa ntchito, makamaka muzamlengalenga ndi ndege.

(2) kugwiritsa ntchito zida zatsopano zowunikira magetsi

Pure Sc2O3 idasinthidwa kukhala ScI3, kenako idapangidwa kukhala chowunikira chatsopano chamagetsi cham'badwo wachitatu ndi NaI, chomwe chidasinthidwa kukhala nyali ya scandium-sodium halogen yowunikira (pafupifupi 0.1mg~ 10mg ya Sc2O3≥99% zinthu zidagwiritsidwa ntchito pa nyali iliyonse. . Pansi pa mphamvu yamagetsi apamwamba, mzere wa scandium spectral ndi wa buluu ndipo mzere wa sodium spectral ndi wachikasu, ndipo mitundu iwiriyi imagwirizana kuti ipange kuwala pafupi ndi kuwala kwa dzuwa. kupulumutsa mphamvu, moyo wautali ndi mphamvu yamphamvu yoswa chifunga.

(3) Kugwiritsa ntchito zipangizo za laser

Gadolinium gallium scandium garnet (GGSG) ikhoza kukonzedwa powonjezera Sc2O3≥ 99.9% yoyera ku GGG, ndipo kapangidwe kake ndi mtundu wa Gd3Sc2Ga3O12. Mphamvu yotulutsa ya m'badwo wachitatu wa laser yomwe idapangidwa ndi iyo ndiyokwera nthawi 3.0 kuposa ya laser yokhala ndi voliyumu yomweyi, yomwe yafika pa chipangizo champhamvu kwambiri komanso chaching'ono, ndikuwonjezera mphamvu yotulutsa laser oscillation ndikuwongolera magwiridwe antchito a laser. . Pokonzekera galasi limodzi, mtengo uliwonse ndi 3kg ~ 5kg, ndipo pafupifupi 1.0kg ya zipangizo zopangira ndi Sc2O3≥99.9% zimawonjezedwa. Pakadali pano, laser yamtunduwu imagwiritsidwa ntchito kwambiri muukadaulo wankhondo, ndipo imakankhidwiranso pang'onopang'ono kumakampani a anthu wamba. Kuchokera pakuwona kwachitukuko, ili ndi kuthekera kwakukulu muzogwiritsidwa ntchito zankhondo ndi anthu wamba m'tsogolomu.

(4) kugwiritsa ntchito zipangizo zamagetsi

Pure Sc2O3 angagwiritsidwe ntchito ngati makutidwe ndi okosijeni cathode activator kwa cathode elekitironi mfuti ya mtundu TV chithunzi chubu ndi zotsatira zabwino. Utsi wosanjikiza wa Ba, Sr ndi Ca okusayidi ndi makulidwe a millimeter imodzi pa cathode wa mtundu chubu, ndiyeno kumwazikana wosanjikiza Sc2O3 ndi makulidwe a 0,1 millimeter pamenepo. Mu cathode ya oxide wosanjikiza, Mg ndi Sr amachita ndi Ba, zomwe zimalimbikitsa kuchepetsa Ba, ndi ma elekitironi omasulidwa akugwira ntchito kwambiri, akupereka magetsi akuluakulu amakono, omwe amachititsa phosphor kutulutsa kuwala. Poyerekeza ndi cathode popanda Sc2O3 kupaka. , ikhoza kuonjezera kachulukidwe kameneka ka 4, kupanga chithunzi cha TV kukhala chomveka bwino ndikutalikitsa moyo wa cathode ndi maulendo atatu. Kuchuluka kwa Sc2O3 komwe kumagwiritsidwa ntchito pa 21 inchi yomwe ikutukuka cathode ndi 0.1mg Pakalipano, cathode iyi yakhala ikugwiritsidwa ntchito m'mayiko ena padziko lapansi, monga Japan, zomwe zingathe kupititsa patsogolo mpikisano wamsika ndikulimbikitsa malonda a ma TV.
