SiffofinCerium Boride:
Dukiya: Cerium hexaborate (CeB6, kuma aka sani da cerium borate, CeBix, CEBIX, wani lokacin ana rubutawa azaman CeB) wani fili ne na inorganic. Cerium hexaborate (CeB6) yana da tsarin CsCl (na na tsarin kristal mai sauƙi, tare da manyan sassan da ke wakiltar ɓangaren Ce). Bambanci shine cewa gungu na octahedral B6 sun mamaye matsayin Cl, yayin da Ce ya mamaye matsayin Cs.
Kayan yumbu mai jujjuyawa ne tare da ƙaramin aikin aiki, yana mai da shi ɗaya daga cikin sanannun kayan cathode tare da mafi girman iskar lantarki, kuma yana da ƙarfi sosai a cikin injin. Yanayin aiki na yau da kullun na cerium hexaborate shine 1450 ° C. Cerium hexaborate, kamar lanthanum hexaborate, sannu a hankali zai ƙafe yayin aikin cathode.
CeB6 cathode na iya kula da mafi kyawun siffarsa na tsawon lokaci a yanayin zafin aiki na 1850 K, yana haifar da tsawon rayuwa. A halin yanzu, saboda yawan ƙawancewar sa kusan kashi 30% a hankali fiye da na lanthanum borate, murfin cathode na cerium borate shima ya fi wahalar cirewa fiye da lanthanum borate.

Aikace-aikacen Cerium Boride:
An fi amfani da Cerium boride azaman rufi don cathodes masu zafi, ko kuma cathodes masu zafi sun ƙunshi lu'ulu'u na cerium hexaborate kai tsaye. Cerium hexaboride (CeB6) da lanthanum hexaboride (LaB6) ana amfani da su azaman babban suturar cathode na yanzu. Hexaborides suna da ƙaramin aikin aiki, a kusa da 2.5 eV, kuma suna da takamaiman haƙuri ga gurɓataccen cathode. Cerium boride cathodes suna da ƙarancin ƙanƙara mai ƙanƙara fiye da lanthanum boride a 1700 K, amma sun zama daidai a 1850 K kuma har ma suna da ƙimar ƙashin ƙasa sama da wannan zafin jiki.
Cerium boride cathode yana da tsawon rayuwa 50% fiye da lanthanum boride saboda girman juriya ga gurɓataccen carbon. Hasken cathode na boride ya ninka na tungsten cathode sau goma, kuma tsawon rayuwarsa ya ninka sau 10-15 na tungsten cathode. Wasu gwaje-gwajen dakin gwaje-gwaje sun nuna cewa CeB6 ya fi haƙuri ga mummunan tasirin gurɓataccen carbon fiye da LaB6. Ana yawan amfani da su a fagage kamar su microscopes na lantarki, bututun microwave, etching na lantarki, walda igiyar lantarki, bututun X-ray, da Laser na lantarki kyauta.
Cerium hexaboride (CeB6) wani abu ne na cathode tare da matsanancin iskar wutar lantarki saboda ƙarancin aikin sa. Ya fi juriya ga gurɓataccen carbon kuma yana da tsawon rayuwa fiye da lanthanum borate cathodes. Ana amfani da shi sosai a fagage kamar microscopy na lantarki, bututun microwave, etching na lantarki, walƙiya katako na lantarki, bututun X-ray, da Laser na lantarki kyauta. An yi nasarar amfani da lu'ulu'u na cerium hexaborate a cikin na'urorin lantarki na lantarki na tebur, sun zama kyawawan kayan filament masu tsayi.
