I-China Subsier Certium Hexaboride Powder Case 12008-02-5 CEB6 PREACK CEREUID
Imininingwane emfushane:
Izici zeI-Cerium Boride:
Impahla: I-Cerrium Hexabooute (CEB6, eyaziwa nangokuthi i-Cerrium Boute, CEBIX, CEBIX, ngesinye isikhathi ibhalwe njenge-CEB) iyindawo yokuqamba. I-Cerium Hexabooute (CEB6) inesakhiwo se-CSCL (esingowohlelo olulula lweCubic Crystal System, olunemikhakha emikhulu emele into ye-CE). Umehluko ukuthi amaqoqo we-B6 Octahedral ahlala esikhundleni se-CL, ngenkathi uCE athatha isikhundla se-CS.
Kuyinto ebonakalayo ye-ceramic yomsebenzi onomsebenzi ophansi, okwenza kube ngenye yezinto ezaziwayo ze-cathode ezinama-elektroni aphezulu kakhulu we-elektroni, futhi kuzinze futhi ku-vacuum. Ukushisa okujwayelekile kokusebenza kwe-certium hexabooute kungu-1450 ° C. certium hexabooute, afana noLanthanum Hexabooute, uzohwamuka kancane ngesikhathi sokusebenza kweKathode.
I-CEB6 CHATODE CHOOD ingalondoloza ukwakheka okuphezulu isikhathi eside sesikhathi sokushisa okusebenzayo kwe-1850 K, okuholela ekuphila isikhathi eside. Ngaleso sikhathi, ngenxa yesilinganiso saso sokuhwamuka kwaso sihamba nge-30% ehamba kancane kunalokho kweLanthanum Boul, i-Chethdode Coating of Cerrium Booster nayo inzima ukuyikhipha ku-Lanthanum Bolay.

Ukusetshenziswa kwe-certium boride:
I-Cerium Boride isetshenziswa ikakhulukazi njengenhlanganisela ye-cathode eshisayo, noma ama-cathode ashisayo ahlanganiswa ngqo namakristalu e-certium hexabac. I-Cerium Hexaboride (CEB6) neLanthanum Hexaboride (Lab6) zivame ukusetshenziswa njengezinkukhu zamanje ze-cathode yamanje. Ama-Hexaborides anomsebenzi ophansi womsebenzi, cishe ngo-2,5 eV, futhi abekezelele ukubekezelela okuthile kuChethade kungcoliswa. Ama-Cathodes we-CERCIEM BORDIDE anezinga eliphansi lokuhwamuka kune-lanthanum boride ngo-1700 k, kepha azithobekile ngo-1850 K futhi aze abe nezinga eliphakeme lokuhwamuka ngaphezulu kwalelo lokushisa.
I-CERTIEMIEM BORDIDE CHATODE inesiphi isikhathi esingu-50% sokuphila kune-lanthanum boride ngenxa yokumelana kwayo okuphezulu ngenxa yokungcola kwekhabhoni. Ukukhanya kwe-cathode ye-boride amahlandla ayishumi eTungsten Choode, kanye nesikhathi sayo sokuphila kungu-10-15 izikhathi zeChodi yeTungsten. Ezinye izivivinyo zelebhu zikhombise ukuthi i-CEB6 ibekezelela kakhulu emiphumeleni engemihle yokungcoliswa kwekhabhoni kune-Lab6. Zivame ukusetshenziswa emikhakheni efana nezinto microscon
I-Cerrium hexaboride (CEB6) iyinto ebonakalayo ye-cathode enezinto eziphakeme kakhulu ze-electron ngenxa yomsebenzi wayo ophansi womsebenzi. Kumelana kakhulu nokungcoliswa kwekhabhoni futhi kunesikhathi sokuphila eside kune-lanthanum Book Cathode. Isetshenziswa kabanzi emasimini afana ne-elektroni microscopy, amashubhu we-microwave, i-elektroni etching, i-electron beam welding, amashubhu we-x-ray, nama-elektroni wamahhala. Amakristalu e-cerium hexabute asetshenziswe ngempumelelo kwi-desktop ukuskena ama-microscopes we-elektroni, abe yizinto ezinhle kakhulu nezizinzile zezinto ezizinzile.
