I roto i te mara ahumahi pāmahana-tiketike, he wāhanga matua tēnei e rite ana te hiranga ki te ngākau o ngā taputapu – koia tepūwero karawiti silicon. Ko tēnei wāhanga ahumahi i hangaia mā te whakamahi i te hangarau uku matatau kei te whakarato i te tautoko hiko pumau me te pono mō ngā taputapu maimoatanga pāmahana teitei. Me hurahia te arai ngaro o tēnei hangarau pango ahumahi.
1, He mahi tino pai te hanga patu ahumahi
1. Ātete pāmahana tino kaha: Ka mau tonu te āhua pumau o tēnei rauemi ahakoa i raro i te wera nui o te 1350 ℃, ā, ka taea te tu atu i ngā pāmahana e rite ana ki te pāmahana o te magma i te wā o ngā puia. Ko ngā taiao pāmahana tino tiketike pērā i ngā oumu ahumahi me te whakarewa whakarewa ngā papa pakanga matua.
2. Whakangungu matū: I te aroaro o te mimiti tonu mai i ngā wairewa waikawa me te kawakore, ka hangaia he paparanga tiaki taiao ki runga i te mata o te silicon carbide, ka taea te pupuri i te hanganga pumau ahakoa i roto i ngā taiao whakaputa tino kino o ngā umanga matū.
3. Tinana o te Taimana: Ko tōna pakeke te tuarua o te taimana, ā, i raro i te mimiti tere-rahi o te mura mō te wā roa, kāore he tohu o te kakahu i runga i te mata, e whakarite ana i te mahi tonu o te taputapu me te kore e whakakapia pinepine.
4. Tohunga kawe wera: Nā te hanganga karaihe ahurei ka nui ake te pai o te kawe wera i te maitai noa, pērā i te whakataurite pāmahana kua hangaia, ka ōrite ake te tohatoha wera i ngā kokonga katoa o te oumu.
2. Te mea ngaro pūtaiao o te hoahoa atamai
Kei roto i te hoahoa auaha o te pūwero silicon carbide te mātauranga hangarau tino pai. Ka whakamahia e te rūma mura he hanganga kua arotauhia te hihiri wai, e āhei ai te mura ki te whakaranu me te tahu i roto i tētahi wāhi motuhake. Ko te hoahoa putanga kōniko ahurei ka whakanui ake i te tere o te putanga hau, ehara i te mea ka whakarei ake i te pai o te whakawhiti wera anake, engari ka whai hua hoki ki te whakaiti i te rere o te hau i te pāmahana teitei me te karo i te wera nui o te rohe. Mā tēnei hoahoa ka rite te pūnaha mura katoa ki tētahi tira waiata pāmahana tika, e ārahi ana i te rere tika o te kaha wera i roto i te taputapu.
3, Paearu hou mō ngā tono whakawhiti-mātauranga
Mai i te whakamahana whakarewa ki te whakakā uku, mai i te hanga matū ki te tahunga taiao, kei te hurihia e ngā pūwero karawiti silicon ngā paerewa whakaputa o ngā ahumahi pāmahana teitei. Ehara i te mea ka roa ake te roa o te mahi a ngā taputapu, engari ka puta mai hoki he painga nui ki ngā umanga ki te penapena pūngao mā te whakapai ake i te pai o te wera. I roto i te horopaki o te whāinga "waro takirua", kei te noho tēnei hangarau hei kaha nui mō te whakapai ake i ngā ahumahi tuku iho.
Hei paionia hangarau e aro nui ana ki te ao o ngā uku motuhake, ka arotau tonu mātou i te tukanga whakarite o ngā pūwero mura silicon carbide, ā, mā roto i ngā hangarau patent, ka tino whakarei ake i te mahi hua ki te whakataurite ki ngā tukanga tuku iho. Ka whakamatautauria ia hua kia tiakina ai ngā taumata pāmahana teitei katoa i roto i te hanga ahumahi me te kounga pono.
Ko tēnei whakatutukitanga auaha o te whakauru i te pūtaiao rauemi me te hangarau wera kei te whakarato i ngā otinga pūngao wera haumaru ake, whai hua ake hoki mō te rāngai ahumahi o te ao. I tēnei wā hou o te hanga atamai, ka haere tonu ngā pūwero silicon carbide ki te whakakā i te miihini hou o te whakapai ake ahumahi me te mura o te hangarau.
