Chithunzi Chodziwika cha Europium(III) Oxide

Okisidi ya Europium(III)

Kufotokozera Kwachidule:

Europium(III) Oxide (Eu2O3)ndi mankhwala opangidwa ndi europium ndi mpweya. Europium oxide ilinso ndi mayina ena monga Europia, Europium trioxide. Europium oxide ili ndi mtundu woyera ngati pinki. Europium oxide ili ndi mapangidwe awiri osiyana: cubic ndi monoclinic. Europium oxide yomangidwa ndi cubic ili pafupifupi yofanana ndi kapangidwe ka magnesium oxide. Europium oxide ili ndi kusungunuka kochepa m'madzi, koma imasungunuka mosavuta mu ma acid amchere. Europium oxide ndi chinthu chokhazikika pa kutentha chomwe chili ndi malo osungunuka pa 2350 oC. Kapangidwe ka Europium oxide kogwira ntchito kwambiri monga mphamvu zamaginito, kuwala ndi kuwala kumapangitsa kuti chinthuchi chikhale chofunikira kwambiri. Europium oxide ili ndi mphamvu yoyamwa chinyezi ndi carbon dioxide mumlengalenga.

Kodi Europium(III) Oxide imagwiritsidwa ntchito pa chiyani?

Europium(III) Oxide (Eu2O3) imagwiritsidwa ntchito kwambiri ngati phosphor yofiira kapena yabuluu m'ma TV ndi nyali za fluorescent, komanso ngati choyambitsa ma phosphor okhala ndi yttrium. Ndi chinthu chogwiritsidwanso ntchito popanga magalasi a fluorescent. Europium fluorescence imagwiritsidwa ntchito mu ma phosphor oletsa kupanga zinthu zabodza mu ndalama za ku Euro. Europium oxide ili ndi mphamvu yayikulu yogwiritsira ntchito kuwala kwa dzuwa powononga zinthu zodetsa zamoyo.
