Kev siv scandium oxide hauv cov khoom siv hluav taws xob
Ntshiab Sc2O3 tuaj yeem siv los ua tus activator rau oxidation cathode ntawm cathode electron phom ntawm cov xim TV duab raj, thiab cov nyhuv zoo dua. Txau ib txheej ntawm Ba, Sr thiab Ca oxide nrog lub thickness ntawm 2 hli nyob rau sab sauv kawg ntawm cov xim raj cathode, thiab ces disperse ib txheej ntawm Sc1O2 nrog ib tug tuab ntawm 3.0 hli rau nws. Hauv oxide cathode, cov tshuaj tiv thaiv ntawm Mg, Sr thiab Ba txhawb kev txo qis ntawm Ba. Cov hluav taws xob tso tawm ntau dua thiab tawm cov hluav taws xob loj tam sim no los ua kom cov phosphor ci. Piv nrog rau cov cathode yam tsis muaj Sc3O4 txheej, qhov ceev tam sim no tuaj yeem nce 3 zaug. Daim duab TV tau pom meej dua thiab lub neej cathode tau nce los ntawm ob zaug. Tus nqi ntawm Sc21O0 siv rau txhua 3-inch kev loj hlob cathode yog 1.<>mg. Tam sim no, cov cathode no tau siv nyob rau qee lub tebchaws hauv ntiaj teb, xws li Nyiv, uas tuaj yeem txhim kho kev lag luam kev sib tw thiab txhawb kev muag TV.
