Ina tipu te tioata karawiti silicon, ka rerekē te "taiao" o te atanga tipu i waenga i te pokapū tuaka o te tioata me te taha, kia piki ake ai te ahotea tioata i te taha, ā, he ngāwari ki te whakaputa i ngā "hapa whānui" i te taha tioata nā te awe o te mowhiti aukati karāpeti "waro", me pēhea te whakaoti rapanga taha, te whakanui ake rānei i te horahanga whai hua o te pokapū (neke atu i te 95%) he kaupapa hangarau nui.
I te mea kei te whakahaeretia haeretia e te ahumahi ngā hapa nui pēnei i te "microtubules" me te "inclusions", e whakawero ana i ngā tioata silicon carbide ki te "tipu tere, roa me te matotoru, me te tipu ake", ka tino kitea ngā "hapa whānui" o te taha, ā, i te pikinga ake o te diameter me te matotoru o ngā tioata silicon carbide, ka whakareatia ngā "hapa whānui" o te taha ki te tapawhā diameter me te matotoru.
Ko te whakamahinga o te paninga tantalum carbide TaC he whakaoti rapanga taha me te whakapai ake i te kounga o te tipu tioata, koinei tētahi o ngā aronga hangarau matua o te "tipu tere, te tipu matotoru me te tipu ake". Hei whakatairanga i te whanaketanga o te hangarau ahumahi me te whakaoti i te whakawhirinaki "kawemai" o ngā rauemi matua, kua whakatauhia e Hengpu te hangarau paninga tantalum carbide (CVD) me te eke ki te taumata matatau o te ao.
Mai i te tirohanga o te whakatinanatanga, ehara i te mea uaua te paninga tantalum carbide TaC, engari he ngāwari te whakatutuki i ngā tikanga sintering, CVD me ētahi atu. Ko te tikanga sintering, ko te whakamahi i te paura tantalum carbide, i te matū rānei, me te tāpiri i ngā kai hohe (te nuinga o te konganuku) me te kaihoko here (te nuinga o te polymer mekameka roa), ka pania ki te mata o te papa graphite kua sinted i te pāmahana teitei. Mā te tikanga CVD, i whakatakotoria te TaCl5+H2+CH4 ki runga i te mata o te matrix graphite i te 900-1500℃.
Heoi, he tino uaua ngā tawhā taketake pēnei i te takotoranga tioata o te whakatakotoranga tantalum carbide, te matotoru kiriata ōrite, te tukunga ahotea i waenga i te paninga me te anga graphite, ngā kapiti mata, me ētahi atu. Ina koa i roto i te taiao tipu tioata, ko te roa o te ora ratonga pumau te tawhā matua, koinei te mea tino uaua.
