Kugwiritsa ntchito scandium oxide

The chemical chilinganizo chascandium oxidendi 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). Zogulitsa za scandium zili ndi luso lothandiza komanso labwino pazachuma.Sc2O3 yakhala ikugwiritsidwa ntchito kwambirialuminiyamu aloyi, gwero lamagetsi lamagetsi, laser, chothandizira, activator, ceramics, 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

Pakali pano, Al-Sc aloyi zopangidwa ndi Sc ndi Al ali ndi ubwino otsika osalimba (SC = 3.0g/cm3, Al = 2.7g/cm3, mkulu mphamvu, mkulu kuuma, plasticity wabwino, kukana dzimbiri amphamvu ndi matenthedwe bata, etc. Choncho, wakhala bwino ntchito mu structural mbali za mivi, ndege ndi ndege, anatembenukira pang'onopang'ono ndi ndege, ndege ndi ndege. kugwiritsa ntchito, monga zogwirira ntchito zamasewera (hockey ndi baseball)Ili ndi mawonekedwe amphamvu kwambiri, kusasunthika kwakukulu komanso kulemera kopepuka, ndipo ndiyothandiza 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 wapanga mndandanda wa aloyi angapo, mwachitsanzo, Russia yafika mitundu 17 ya mndandanda wa 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

KoyeraChithunzi cha Sc2O3idasinthidwa kukhala SCI3, kenako idapangidwa kukhala gwero lamagetsi lamagetsi lachitatu ndi NaI, yomwe idasinthidwa kukhala nyali ya scandium-sodium halogen yowunikira (pafupifupi 0.1mg ~ 10mg ya Sc2O3≥99% zakuthupi idagwiritsidwa ntchito pa nyali iliyonse. pafupi ndi kuwala kwa dzuwa.Kuwala kuli ndi ubwino wa kuwala kwakukulu, mtundu wabwino wa kuwala, kupulumutsa mphamvu, moyo wautali ndi mphamvu zowononga chifunga.

(3) Kugwiritsa ntchito zida 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 yopangidwa ndi iyo ndi yokwera 3.0 kuposa ya laser yokhala ndi voliyumu yomweyi, yomwe yafika pa chipangizo champhamvu champhamvu komanso chaching'ono, ndikuwonjezera mphamvu yakutulutsa kwa 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. Uza wosanjikiza wa Ba, Sr ndi Ca oxide ndi makulidwe a millimeter imodzi pa cathode wa mtundu chubu, ndiyeno kumwaza wosanjikiza waChithunzi cha Sc2O3ndi makulidwe a 0,1 millimeter pamenepo. Mu cathode ya oxide wosanjikiza, Mg ndi Sr amachitira ndi Ba, zomwe zimalimbikitsa kuchepetsa Ba, ndi ma elekitironi omasulidwa ndi yogwira ntchito, kupereka ma elekitironi lalikulu panopa, zomwe zimapangitsa phosphor kutulutsa kuwala.Poyerekeza ndi cathode popanda Sc2O3 ❖ kuyanika, akhoza kuonjezera kachulukidwe panopa ndi 4 nthawi, kupanga TV chithunzi momveka nthawi 3 cathode ndi pro. 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.
