Tuam Tshoj Tsum Cerium Hexaboride CAS 12008-02-5 Ceb 6 Hmoov Ch Cerium Bornide
Cov Lus Qhia Luv:
Nta ntawmCERINE BORIDIDE:
Cov cuab yeej: cerium hexaborate (raum, tseem paub tias yog borium borate, Cexix, qee zaum sau ua Ceb) yog qhov sib xyaw ua ke inorganic. Cerium Hexabnate Hexabnate (Ceb6) muaj CSCL qauv (yog rau ib qho yooj yim cubic crystal system, nrog cov spheres loj sawv cev rau lub sijhawm CE). Qhov sib txawv yog tias b6 octahedral pawg nyob ntawm ntug kev ntawm cl, thaum CE occupies txoj haujlwm ntawm CS.
Nws yog cov refractory tej hub khoom nrog txoj haujlwm ua haujlwm qis dua, ua rau ib qho ntawm cov ntaub ntawv uas paub txog hluav taws xob nrog lub zog hluav taws xob zoo nkauj, thiab nws tseem muaj zog heev hauv lub tshuab nqus tsev. Cov ntsuas cua sov ntawm cerium hexaborate yog 1450 ° C cerium hexaborate, zoo li Libthanum hexaborate hexaborate, yuav maj mam yaj thaum lub sijhawm ua haujlwm.
Lub Ceb6 Cathode tuaj yeem tswj nws cov qauv zoo tshaj plaws rau lub sijhawm ntev dua ntawm kev ua haujlwm kub ntawm 1850 k, ua rau muaj lub neej ntev. Lub caij no, vim nws cov evaporation tau li 30% qeeb dua li ntawm kev sib tw cerium kuj tseem nyuaj dua li Lanthhanum borate.
Cov ntaub ntawv txheej txheem ntawm Ceeline buride:

Daim ntawv thov ntawm Cerium buride:
Cerium laj kab yog tsuas yog siv los ua txheej rau kub Cathodes, lossis kub Cathodes tau ncaj qha rau Cerium Hexab. Cerium hexaboride (Ceb6) thiab Lanthant Hexaboride (lab-lab) feem ntau siv raws li cov txheej txheem cathode tam sim no. Hexaborides muaj txoj haujlwm ua haujlwm qis dua, nyob ib ncig ntawm 2.5 EV, thiab muaj qee qhov tsis taus rau Cathode kev sib kis. Cerium doride talide tus nqi qis dua lilthehanum buride nyob rau xyoo 1850 k, tab sis lawv tau muaj lub siab evaporation siab dua qhov ntsuas kub.
Cerium boride cathode muaj lub neej ntev dua lilthhanum boride vim nws lub siab kuj tsis kam mus rau cov kab mob ua qias tuaj. Qhov ci ntsa iab ntawm ib sab cathode yog kaum lub sij hawm ntawm tungsten cathode, thiab nws lub neej yog 10-15 zaug uas ntawm tungsten cathrode. Qee lub chaw kuaj sim tau qhia tau tias Ceb6 yog kev zam txim ntau dua rau qhov tsis zoo ntawm cov pa hluav taws xob tsis zoo. Lawv feem ntau yog siv nyob rau hauv cov liaj teb xws li hluav taws xob tsom iav, microwave hlab, electron nqaj vuam, xoo hluav taws xob av, thiab dawb electron nqaj.
Cerium hexaboride (Ceb6) yog cov khoom siv Cathode nrog cov hluav taws xob tsis tshua muaj zog vim nws txoj haujlwm ua haujlwm qis. Nws yog tiv thaiv ntau ntxiv rau cov kab mob ua qias tuaj thiab muaj lub neej ntev dua lilthhanum borate cathodes. Nws yog dav siv nyob rau hauv cov liaj teb xws li electron me me, microwave hlab, electron nqaj vuam, xoo hluav taws xob av, thiab dawb electron Cerium Hexab xibtes muaju tau ua tiav zoo nyob rau hauv desktop scanning hluav taws xob cov ntaub ntawv, ua cov ntaub ntawv zoo nkauj.
