I roto i te pūnaha matatini o te ahumahi hou, he maha ngā tukanga whakaputa matua e whakawhirinaki ana ki ngā rauemi me ngā wāhanga iti noa iho engari he mea nui. Ko ngā roera silicon carbide tētahi o aua mea. Ahakoa he iti noa iho, he mahi nui tana i roto i ngā mara ahumahi pāmahana teitei, ā, ka taea te kī ko ia te toa i muri i ngā whakaaturanga o te ahumahi pāmahana teitei.
Roera waro silicon, e ai ki tōna ingoa, ko tōna wāhanga matua ko te silicon carbide (SiC). Ko te silicon carbide he matū hangahanga e whakakotahi ana i ngā āhuatanga o te waro me te silicon hei hanga i tētahi raupapa o ngā āhuatanga tino pai. He tino pakari tēnei rauemi, tuarua ki te taimana anake, ā, he pai te ātete ki te kakahu, pērā i te hōia e mau ana i te pukupuku, ka taea e ia te pupuri i tōna āhua ahakoa i roto i ngā taiao mahi uaua. I taua wā anō, he tino pai hoki tōna ātete ki te pāmahana teitei, ā, ka taea te mahi pumau mō te wā roa i ngā pāmahana teitei me te kore e ngāwari te huri, te kino rānei. Nā tēnei ka tū motuhake ngā roera silicon carbide i roto i te umanga pāmahana teitei, ā, ka noho hei rauemi pai mō te maha o ngā umanga.
I roto i te umanga uku, ka kitea te aroaro o ngā roera silicon carbide i ngā wāhi katoa. I roto i te tukanga tahu uku, me whakawera te tinana uku i roto i te oumu pāmahana-teitei kia whakakīkī ai, kia whiwhi ai i ngā āhuatanga e hiahiatia ana. He mahi nui tā te roera silicon carbide ki te tautoko me te kawe i roto i tēnei tukanga. Ka taea e ia te tu atu i te pēhanga nui i roto i ngā taiao pāmahana-teitei, kia pai ai te nekehanga me te whakamahana ōrite o ngā tinana uku i roto i ngā oumu, kia pai ai te kounga me te ōrite o ngā hua uku. Ki te whakatauritea ki ngā rauemi roera tuku iho, he roa ake te ora o ngā roera silicon carbide, ka taea ai te whakaiti i te auau o te whakakapinga roera, te whakaiti i ngā utu whakaputa, me te whakapai ake i te pai o te whakaputa.
I roto i te umanga hanga karāhe, he mahi nui anō tā ngā roera silicon carbide. I roto i te tukanga hanga me te tukatuka karāhe, me totoro me te pēhi i te wai karāhe i ngā pāmahana teitei hei hanga i ngā momo āhua o ngā hua karāhe. Ka taea e ngā roera silicon carbide te pā atu ki te karāhe rewa i ngā pāmahana teitei me te kore e pāngia e ngā tauhohenga matū, kia mau ai te parakore me te kounga o te karāhe. I taua wā anō, mā tōna ātete kakahu teitei ka taea e te roera te pupuri i te maeneene o te mata i muri i te whakamahinga roa, kia mau ai te kounga o te mata o ngā hua karāhe.
Haunga ngā ahumahi uku me te karāhe, he whānuitia hoki te whakamahinga o ngā roera silicon carbide i roto i ngā mara pēnei i ngā semiconductors, te tukatuka whakarewa, me te paura metallurgy. I roto i te hanga semiconductors, ka whakamahia mō te whakakanapa me te whakawhiti i ngā anga silicon, kia tino tika ai te hanga o ngā taputapu semiconductors; I roto i te tukatuka whakarewa, ka whakamahia mō te hurihuri pāmahana teitei me te maimoatanga wera, e whakapai ake ana i te mahi me te kounga o ngā rauemi whakarewa; I roto i te paura metallurgy, ka whakamahia mō te pēhi paura me te sintering, e whakatairanga ana i te whakakīkī rauemi me te arotautanga mahi.
I te haere tonu o te hangarau me te tere o te whanaketanga o te ahumahi, kei te piki haere hoki ngā whakaritenga mahi mō ngā roera silicon carbide. Hei whakatutuki i ēnei hiahia, kei te haumi tonu ngā kairangahau me ngā umanga ki te auahatanga hangarau me te rangahau me te whanaketanga. Mā te whakapai ake i ngā tukanga whakaputa me ngā tauira, ka whakarei ake te mahi me te kounga o ngā roera silicon carbide, ka nui ake te ātete ki ngā pāmahana teitei, te kakahu, te waikura, ā, ka taea te urutau ki ngā taiao mahi uaua ake, uaua ake hoki.
Ahakoa te āhua noa o te āhua, he mea nui ngā roera silicon carbide i roto i te ahumahi pāmahana teitei, engari he mahi nui tonu tā rātou i roto i ngā momo mara. Nā tōna mahi tino pai me te whānui o te whakamahinga, ka tautokohia te whanaketanga o te ahumahi hou. I te heke mai, me te auahatanga tonu o te hangarau me te whānui haere o ngā mara tono, e whakapono ana mātou ka tukuna tonutia e ngā roera silicon carbide te māramatanga me te wera i roto i ngā ahumahi pāmahana teitei, ka nui ake te uara.
