Ukukhetha I-Graphite Crucible Efanele Yokukhula Kwekristalu: Umhlahlandlela Owusizo
Ezweni lokukhula kwekristalu—kungakhathaliseki ukuthi kwe-SiC, i-GaN, i-sapphire, noma ezinye izinto ezithuthukisiwe—i-graphite crucible akuyona nje isitsha. Ingumngcele wokushisa, isikhombimsebenzisi sokusabela, kanye nomlindi wesango lokuhlanzeka. Ukukhetha i-crucible efanele kungathinta kakhulu isivuno, ikhwalithi yekristalu,...Funda kabanzi -
Umhlahlandlela Wokukhetha I-Graphite Embozwe Nge-TaC
Emishinini yokukhula kwekristalu eshisa kakhulu kanye ne-epitaxy/deposition, i-graphite crucible idlala izindima ezintathu ngesikhathi esisodwa: umngcele wokushisa, isikhombimsebenzisi sokusabela, kanye nomthombo wokungcola/umgoqo wokungcola okungenzeka. Yingakho i-graphite crucibles ene-TaC egcotshwe yi-TaC ivame kakhulu—i...Funda kabanzi -
Kungani Izitsha Zokubumba Ezimbozwe Nge-SiC Zinquma Ukukhiqizwa Okuqinile Kwesisindo?
Emigqeni yokukhiqiza ukukhula kwekristalu ye-SiC, onjiniyela abaningi bagxila ekwakhiweni kwezindawo ezishisayo, ama-curve okulawula izinga lokushisa, kanye nokwakheka kwempuphu. Kodwa-ke lapho kuvela ukuguquguquka kwesivuno, imbangela eyinhloko ivame ukubuyela emuva entweni efanayo—i-crucible. Ayikhiphi ukukhanya, ayijikelezi, futhi ayibonakali...Funda kabanzi -
Kuyini i-MOCVD SiC Coated Heater
I-MOCVD (i-Metal-Organic Chemical Vapor Deposition) iyindlela esetshenziswa kabanzi yokubeka ifilimu encane esezingeni eliphezulu futhi idlala indima ebalulekile embonini yokukhiqiza ye-semiconductor kanye ne-electronics. Njengengxenye ebalulekile enqubweni ye-MOCVD, ama-heater ambozwe yi-SiC avame ukusetshenziswa ukusekela...Funda kabanzi -
Izinga Lokushisa Eliphezulu Le-Graphite Element: Yini Eyikhawulela Emoyeni Uma Iqhathaniswa Ne-Vacuum?
Izinto zokushisa ze-graphite, njengamadivayisi okushisa okushisa okuphezulu, zisetshenziswa kabanzi ezimbonini eziningi, kufaka phakathi i-metallurgy, i-electronics, i-semiconductors, kanye namakhemikhali. Izinto ze-graphite zinokuqhutshwa kokushisa okuhle kakhulu, ukumelana nokushisa okuphezulu, kanye nokuqina kwamakhemikhali, okuvumela ukuthi zigcine...Funda kabanzi -
Ukusetshenziswa kwe-Graphite Felt yebhethri lokugeleza
Emkhakheni wokugcina amandla okuthuthukisiwe, amabhethri okugeleza avele kancane kancane njengesixazululo esingandiswa futhi esihlala isikhathi eside, ikakhulukazi ekusetshenzisweni okumile njengokulinganisela kwegridi, ukuhlanganiswa kwamandla avuselelekayo, kanye nezinhlelo zokusekela zezimboni. Phakathi kwezinto eziyinhloko ezinquma ukusebenza...Funda kabanzi -
Ukusetshenziswa kwe-Graphite Battery Felt kuma-Flow Batteries kanye nama-Fuel Cells
I-graphite battery felt idlala indima ebalulekile kubuchwepheshe bebhethri besimanje, ikakhulukazi kumabhethri okugeleza kanye namaseli kaphethiloli. Njengento ephumelelayo nehlala isikhathi eside, i-graphite felt inikeza ugesi omuhle kakhulu kanye nokuzinza kokushisa, ngenkathi futhi inikela ekusebenzeni kwebhethri okuthuthukisiwe, isibonelo...Funda kabanzi -
Kuyini i-Graphite Electrode Felt?
I-graphite electrode felt iyinto esuselwe ku-carbon enezimbobo, engashisi kakhulu esetshenziswa kabanzi ekusetshenzisweni kwe-electrochemical, ikakhulukazi ezinhlelweni zokugcina amandla kanye nokuguqulwa njengamabhethri okugeleza kwe-redox, amaseli kaphethiloli, kanye nama-reactor e-electrolytic. Ikhiqizwa ngokufaka i-carbonizing kanye ne-graphit...Funda kabanzi -
Kuyini i-SOI?
I-SOI yisifinyezo se-Silicon-On-Insulator. Ngokwezwi nezwi, isho ukuthi “i-silicon ku-insulator.” Empeleni, isakhiwo siwukuthi kukhona ungqimba oluncane kakhulu lokuvikela, njenge-SiO₂, phezu kwe-silicon wafer, bese kwakheka ungqimba oluncane lwe-silicon phezu kwalolu ngqimba lokuvikela.
