Ndi kupanga kwapang'onopang'ono kwa ma conductive SiC substrates, zofunika zapamwamba zimayikidwa patsogolo kuti ntchitoyi ikhale yokhazikika komanso yobwerezabwereza. Makamaka, kuwongolera zolakwika, kusintha pang'ono kapena kugwedezeka kwa malo otentha mu ng'anjo, kudzabweretsa kusintha kwa kristalo kapena kuwonjezeka kwa zolakwika. M'kupita kwa nthawi, tiyenera kukumana ndi vuto la "kukula mofulumira, kwautali ndi wandiweyani, ndi kukula", kuwonjezera pa kusintha kwa chiphunzitso ndi uinjiniya, timafunikiranso zida zapamwamba zakumunda zamafuta monga chithandizo. Gwiritsani ntchito zida zapamwamba, kulitsa makhiristo apamwamba.
Kugwiritsidwa ntchito molakwika kwa zinthu zowonongeka, monga graphite, porous graphite, tantalum carbide ufa, ndi zina zotero m'munda wotentha zidzabweretsa zolakwika monga kuwonjezeka kwa carbon. Komanso, mu ntchito zina permeability wa porous graphite sikokwanira, ndipo mabowo owonjezera chofunika kuonjezera permeability. The porous graphite ndi mkulu permeability amakumana ndi mavuto processing, kuchotsa ufa, etching ndi zina zotero.
VET ikubweretsa m'badwo watsopano wa SiC crystal kukula kwamafuta akumunda, porous tantalum carbide. A dziko kuwonekera koyamba kugulu.
Mphamvu ndi kuuma kwa tantalum carbide ndizokwera kwambiri, ndipo kuzipanga porous ndizovuta. Kupanga porous tantalum carbide yokhala ndi porosity yayikulu komanso chiyero chachikulu ndizovuta kwambiri. Hengpu Technology yakhazikitsa njira yopambana ya tantalum carbide yokhala ndi porosity yayikulu, yokhala ndi porosity yopitilira 75%, yotsogolera padziko lonse lapansi.
Kusefedwa kwa gawo la gasi, kusintha kwa kutentha kwapafupipafupi, kayendetsedwe ka kayendetsedwe kazinthu, kuwongolera kutayikira, etc., kungagwiritsidwe ntchito. Itha kugwiritsidwa ntchito ndi tantalum carbide ina yolimba (compact) kapena tantalum carbide yokutira kuchokera ku Hengpu Technology kupanga zigawo zakomweko zokhala ndi mafunde osiyanasiyana.
Zigawo zina zitha kugwiritsidwanso ntchito.
