Atụmatụ nkeCerium Boride:

Ngwongwo: Cerium hexaborate (CeB6, nke a makwaara dị ka cerium borate, CeBix, CEBIX, mgbe ụfọdụ a na-ede dị ka CeB) bụ ngwakọta inorganic. Cerium hexaborate (CeB6) nwere usoro CsCl (nke nwere sistemu kristal cubic dị mfe, yana nnukwu akụkụ na-anọchi anya ihe Ce). Ihe dị iche bụ na ụyọkọ octahedral B6 nọ n'ọnọdụ Cl, ebe Ce na-anọkwa n'ọnọdụ Cs.

Ọ bụ ihe seramiiki refractory nke nwere ọrụ ọrụ dị ala, na-eme ka ọ bụrụ otu n'ime ihe ndị a ma ama nke cathode nwere oke ikuku elektrọn, yana ọ kwụsiri ike na oghere. Ụdị okpomọkụ na-arụ ọrụ nke cerium hexaborate bụ 1450 Celsius C. Cerium hexaborate, dị ka lanthanum hexaborate, ga-eji nwayọọ nwayọọ na-ekpochapụ n'oge ọrụ cathode.

CeB6 cathode nwere ike idowe ọdịdị ya kachasị mma ruo ogologo oge na okpomọkụ na-arụ ọrụ nke 1850 K, na-ebute ndụ ogologo oge. Ka ọ dị ugbu a, n'ihi na ọnụ ọgụgụ evaporation ya dị ihe dịka 30% ji nwayọọ nwayọọ karịa nke lanthanum borate, mkpuchi cathode thermal nke cerium borate na-esikwa ike iwepụ karịa lanthanum borate.

Ngwa nke Cerium Boride:

A na-ejikarị cerium boride dị ka mkpuchi maka cathodes na-ekpo ọkụ, ma ọ bụ cathodes na-ekpo ọkụ bụ kristal cerium hexaborate mejupụtara. A na-ejikarị Cerium hexaboride (CeB6) na lanthanum hexaboride (LaB6) eme ihe dị ka mkpuchi cathode dị ugbu a. Hexaborides nwere ọrụ ọrụ dị ala, gburugburu 2.5 eV, ma nwee ụfọdụ nnabata maka mmetọ cathode. Cerium boride cathodes nwere ọnụ ọgụgụ evaporation dị ala karịa lanthanum boride na 1700 K, mana ha na-agbanwe agbanwe na 1850 K na ọbụna nwee ọnụego evaporation dị elu karịa okpomọkụ ahụ.

Cerium boride cathode nwere ogologo ndụ 50% karịa lanthanum boride n'ihi nguzogide ya dị elu na mmetọ carbon. Ịcha ọkụ nke boride cathode ji okpukpu iri karịa nke tungsten cathode, ogologo ndụ ya dịkwa okpukpu 10-15 karịa nke tungsten cathode. Ụfọdụ nnwale ụlọ nyocha egosila na CeB6 na-anabata ihe na-adịghị mma nke mmetọ carbon karịa LaB6. A na-ejikarị ha eme ihe n'ọhịa dị ka microscopes eletrọn, tubes microwave, etching beam electron, electron beam welding, x-ray tubes, na laser electron free.

Cerium hexaboride (CeB6) bụ ihe cathode nwere nzipu elektrọn dị oke elu n'ihi ọrụ ya dị ala. Ọ na-eguzogide mmetọ carbon ma nwee ogologo ndụ karịa lanthanum borate cathodes. A na-eji ya eme ihe n'ọtụtụ ebe dị ka microscopy eletrọn, ọkpọkọ microwave, etching beam elektrọn, ịgbado ọkụ elektrọn, tubes X-ray, na laser elektrọn efu. A na-etinye kristal hexaborate cerium nke ọma na desktọpụ na-enyocha microscopes eletrọnịkị, na-aghọ ihe ndị mara mma ma kwụsie ike.
