Zipangizo zatsopano zokulira makristalo a SiC

Ndi kupanga pang'onopang'ono kwa ma substrates a SiC oyendetsera magetsi, zofunikira zapamwamba zimaperekedwa kuti ntchitoyi ikhale yokhazikika komanso yobwerezabwereza. Makamaka, kuwongolera zolakwika, kusintha pang'ono kapena kusuntha kwa gawo lotentha mu ng'anjo, kudzabweretsa kusintha kwa makristalo kapena kuwonjezeka kwa zolakwika. Munthawi yotsatira, tiyenera kukumana ndi vuto la "kukula mwachangu, kwautali komanso kokhuthala, komanso kukula", kuwonjezera pa kusintha kwa chiphunzitso ndi uinjiniya, timafunikanso zipangizo zapamwamba kwambiri zotenthetsera ngati chithandizo. Gwiritsani ntchito zipangizo zapamwamba, pangani makristalo apamwamba.

Kugwiritsa ntchito molakwika zinthu zophikidwa pamoto monga graphite, graphite yokhala ndi porous, ufa wa tantalum carbide, ndi zina zotero m'munda wotentha kumabweretsa zolakwika monga kuwonjezeka kwa carbon integration. Kuphatikiza apo, mu ntchito zina, graphite yokhala ndi porous integration sikokwanira, ndipo mabowo ena amafunika kuti awonjezere permeability. Graphite yokhala ndi porous integration yambiri ikukumana ndi mavuto monga kukonza, kuchotsa ufa, kupukuta ndi zina zotero.

VET yabweretsa mbadwo watsopano wa zinthu zotentha zomwe zimamera ndi SiC crystal field, tantalum carbide yokhala ndi porous. Yayamba padziko lonse lapansi.

Mphamvu ndi kuuma kwa tantalum carbide ndizokwera kwambiri, ndipo kuzipangitsa kukhala ndi mabowo ndizovuta. Kupanga tantalum carbide yokhala ndi mabowo akuluakulu komanso chiyero chachikulu ndizovuta kwambiri. Hengpu Technology yayambitsa njira yatsopano yopangira tantalum carbide yokhala ndi mabowo akuluakulu, yokhala ndi mabowo ambiri a 75%, yomwe ikutsogolera dziko lonse lapansi.

Kusefa kwa gawo la gasi, kusintha kwa kutentha kwa malo, komwe zinthu zikuyenda, kuwongolera kutuluka kwa madzi, ndi zina zotero, kungagwiritsidwe ntchito. Kungagwiritsidwe ntchito ndi tantalum carbide ina yolimba (compact) kapena tantalum carbide yochokera ku Hengpu Technology kuti ipange zinthu za m'deralo zomwe zimakhala ndi kayendedwe kosiyanasiyana ka madzi.

Zigawo zina zitha kugwiritsidwanso ntchito.
