TilmaamahaCerium Boride:

Hantida: Cerium hexaborate (CeB6, oo sidoo kale loo yaqaan cerium borate, CeBix, CEBIX, mararka qaarkood loo qoro CeB) waa iskudhis aan dabiici ahayn. Cerium hexaborate (CeB6) waxay leedahay qaab-dhismeedka CsCl (oo ka tirsan nidaamka crystal cubic fudud, oo leh qaybo waaweyn oo matalaya qaybta Ce). Farqiga ayaa ah in kooxaha B6 octahedral ay ku jiraan booska Cl, halka Ce uu ku jiro booska Cs.

Waa walxo dhoobo ah oo dib u celin ah oo leh shaqo hoose oo shaqo ah, taas oo ka dhigaysa mid ka mid ah qalabka cathode ee la yaqaan ee leh qiiqa elektaroonigga ah ee ugu sarreeya, sidoo kale waa mid aad u deggan vacuum. Heerkulka shaqada caadiga ah ee cerium hexaborate waa 1450 ° C. Cerium hexaborate, sida lanthanum hexaborate, ayaa si tartiib tartiib ah u soo baxaysa inta lagu jiro hawlgalka cathode.

Cathode-ka CeB6 wuxuu sii hayn karaa qaabkiisa ugu fiican muddo dheer isagoo heerkulkiisu yahay 1850 K, taasoo keenta cimri dheer. Dhanka kale, sababtoo ah heerka uumi-baxa oo qiyaastii 30% ka hooseeya kan lanthanum borate, daahan kulaylka cathode ee cerium borate ayaa sidoo kale aad u adag in la saaro lanthanum borate.

Xogta farsamada ee Cerium Boride:

Codsiga Cerium Boride:

Cerium boride waxaa inta badan loo isticmaalaa sida dahaarka loogu talagalay cathodes kulul, ama cathodes kulul waxay si toos ah uga kooban yihiin cerium hexaborate crystals. Cerium hexaboride (CeB6) iyo lanthanum hexaboride (LaB6) ayaa inta badan loo isticmaalaa sida dahaarka sare ee cathode hadda. Hexaborides waxay leeyihiin shaqo hoose oo shaqo ah, qiyaastii 2.5 eV, waxayna leeyihiin dulqaad gaar ah si ay u wasakheeyaan cathode. Cerium boride cathodes waxay leeyihiin heer uumi ka hooseeya kan lanthanum boride oo ah 1700 K, laakiin waxay noqdaan kuwo joogto ah 1850 K oo xitaa waxay leeyihiin heer uumi sare oo ka sarreeya heerkulkaas.

Cerium boride cathode waxay leedahay 50% cimri dherer ka dheer lanthanum boride sababtoo ah caabbinta sare ee wasakhowga kaarboonka. Iftiiminta cathode boride waa toban jeer ka kan cathode tungsten ah, cimrigiisuna waa 10-15 jeer ka mid ah tungsten cathode. Tijaabooyinka shaybaadhka qaarkood ayaa muujiyay in CeB6 ay uga dulqaad badan tahay saamaynta xun ee wasakhowga kaarboonka marka loo eego LaB6. Waxaa caadi ahaan loo isticmaalaa meelaha sida mikroskoobyada elektarooniga ah, tuubooyinka mikrowaytka, alxanka alxanka elektarooniga ah, tuubooyinka raajada, iyo leysarka elektaroonigga ah ee bilaashka ah.

Cerium hexaboride (CeB6) waa walax cathode ah oo leh qiiqa elektarooniga ah ee aad u sarreeya sababtoo ah shaqadiisa hoose ee shaqada. Way adkeysi badan u leedahay wasakhowga kaarboon waxayna leedahay cimri dheer marka loo eego lanthanum borate cathodes. Waxaa si weyn loogu isticmaalaa meelaha sida mikroskoobyada elektarooniga ah, tuubooyinka mikrowave, alxanka alxanka elektarooniga ah, tuubooyinka raajada, iyo leysarka elektaroonigga ah ee bilaashka ah. Kariimaha Cerium hexaborate ayaa si guul leh loogu dabaqay mikroskoobyada elektarooniga ah ee miis-kaanka, iyagoo noqday walxo fiilooyin ah oo aad u wanaagsan oo deggan.
