Nga korero poto:

Nga ahuatanga oCerium Boride:

Taonga: Cerium hexaborate (CeB6, e mohiotia ana ko te cerium borate, CeBix, CEBIX, i etahi wa ka tuhia hei CeB) he puhui parakore. Ko te Cerium hexaborate (CeB6) he hanganga CsCl (no te punaha karaihe putorino ngawari, me nga awhiowhio nui e tohu ana i te huānga Ce). Ko te rereketanga ko te B6 octahedral tautau e noho ana i te tuunga o Cl, i a Ce e noho ana i te waahi o Cs.

Ko te mea he rauemi uku whakakorikori me te iti o te mahi mahi, na te mea ko tetahi o nga rauemi cathode e mohiotia ana me te kaha o te hiko irahiko, a he tino pumau i roto i te korehau. Ko te pāmahana mahi angamaheni o te cerium hexaborate he 1450 ° C. Cerium hexaborate, penei i te lanthanum hexaborate, ka ata whakaeto i te wa e mahi ana te cathode.

Ka taea e te cathode CeB6 te pupuri i tona ahua tino pai mo te wa roa i te pāmahana whakahaere o 1850 K, ka roa ake te oranga. I taua wa, na te mea he 30% te puhoi ake o te reeti whakaetonga i tera o te lanthanum borate, he uaua ake te tango i te paninga cathode waiariki o te cerium borate i te lanthanum borate.

Te tono mo te Cerium Boride:

Kei te nuinga whakamahia Cerium boride hei paninga mo cathodes wera, he tika tito cathodes wera o tioata cerium hexaborate. Ko te Cerium hexaboride (CeB6) me te lanthanum hexaboride (LaB6) ka whakamahia hei paninga cathode teitei o naianei. He iti ake te mahi a te Hexaborides, tata ki te 2.5 eV, he pai te ahua ki te poke cathode. He iti ake te reeti whakaetonga Cerium boride i to lanthanum boride i te 1700 K, engari ka rite tonu ki te 1850 K, a, he teitei ake te reeti whakaetonga ki runga ake i taua pāmahana.

He 50% roa ake te roanga o te katode Cerium boride i to lanthanum boride na te kaha ake o te atete ki te parahanga waro. Ko te kanapa o te cathode boride he tekau nga wa i to te cathode tungsten, a he 10-15 te roa o tona oranga o te cathode tungsten. Ko etahi o nga whakamatautau taiwhanga i whakaatu he pai ake te noho a CeB6 ki nga paanga kino o te parahanga waro i a LaB6. E whakamahia nuitia ana i roto i nga mara penei i te microscopes irahiko, ngongo ngaruiti, te tarai irahiko, te raima hiko, te ngongo X-ray, me nga taiaho hiko kore utu.

Ko te Cerium hexaboride (CeB6) he rauemi cathode me te kaha o te hiko irahiko na te iti o te mahi. He kaha ake te atete ki te parahanga waro me te roa ake o te oranga i nga cathodes lanthanum borate. Kei te whakamahia nuitia i roto i nga mara penei i te microscopy irahiko, nga ngongo ngaruiti, te tarai irahiko, te raima hiko hiko, nga ngongo X-ray, me nga taiaho hiko kore utu. Ko nga tioata hexaborate Cerium kua oti pai te tono ki roto i te papamahi matawai irahiko microscopes, ka tino pai rawa atu, ka mau hei rauemi kakawaea.
