Isuku ryinshi 99,99% Ifu ya Cerium Boride Ifu nigiciro kinini

Umwanya wo gusaba:

Cerium boride ikoreshwa cyane nkigifuniko cya cathodes ishyushye, cyangwa cathode ishyushye igizwe na kristu ya cerium hexaboride.Cerium hexaboride (CeB6) na lanthanum hexaboride (LaB6) ikoreshwa kenshi nka cathode ishyushye cyane.Hexaboride ifite imikorere mike, hafi 2.5 eV, kandi ifite kwihanganira kwanduza cathode.Cerium boride cathodes ifite igipimo cyo guhumeka munsi ya lanthanum boride kuri 1700 K, ariko ihinduka imwe kuri 1850 K ndetse ikanagera no hejuru yo guhumeka hejuru yubushyuhe.Cerium boride cathodes ifite ubuzima burebure bwa 50% kurenza lanthanum boride kubera kurwanya karuboni nyinshi.Umucyo wa cathode ya boride wikubye inshuro icumi iy'umubyimba wa tungsten kandi ubuzima bwayo bukubye inshuro 10-15 ubwa cathode.Ibizamini bimwe bya laboratoire byagaragaje ko CeB6 yihanganira ingaruka mbi ziterwa na karubone kurusha LaB6.Zikoreshwa cyane, kurugero, microscopi ya electron, imiyoboro ya microwave, ibiti bya elegitoroniki, gusudira ibiti bya elegitoronike, imiyoboro ya X-ray, hamwe na lazeri ya elegitoroniki yubusa.Ni ibikoresho bya ceramic byoroshye.
