I roto i te hanga uku, te whakarewa, te ahumahi matū me ētahi atu ahumahi, ko ngā oumu te taputapu matua, ā, ko ngā pou oumu e tautoko ana i te hanganga o roto o ngā oumu, e pikau ana i ngā kawenga pāmahana teitei, ka taea te kī ko te "anga" o ngā oumu. Ka pā tika tā rātou mahi ki te haumaru mahi me te roa o te mahi o ngā oumu. I roto i ngā rauemi pou maha, kua piki haere te rongonui o ngā pou oumu silicon carbide (SiC) i roto i ngā āhuatanga pāmahana teitei ahumahi nā tō rātou ngāwari ki te urutau, e tiaki puku ana i te mahi pumau o ngā oumu.
Tērā pea he māramatanga pōhewa tō te tini o te tangata kingā pou karāhe silicon, engari ka taea te mārama ko rātou te "tautoko matua mārō" i roto i ngā oumu. Ko te karawiti silicon tonu he rauemi kore-whakarewa kaha kore-waro e whakakotahi ana i te ātete pāmahana teitei o ngā uku me te kaha hanganga e tata ana ki ngā konganuku. He mea urutau noa ki te taiao tino kino i roto i ngā oumu, ā, he painga ā-tūturu ngā pou i hangaia mai i a ia ki te tu atu ki ngā pāmahana teitei me ngā kawenga taumaha.
Tuatahi, ko te tino kaha o ngā pou oumu silicon carbide kei roto i tō rātou ātete tino pai ki ngā pāmahana teitei me te ru wera. I te wā e whakahaerehia ana te oumu, ka taea e te pāmahana o roto te eke ki ngā rau, ki ngā mano rānei nekehanga Celsius, ā, ka tino rerekē te pāmahana i te wā e whakamahana ana, e whakamatao ana hoki. Ka ngawari te pakaru me te hurihanga o ngā pou rauemi noa nā te whānui me te whakaheke wera i roto i tēnei taiao, ka hua ake he hanganga oumu kore pumau. He tino pai te pumau wera o te rauemi silicon carbide, ka taea te tu atu i te tunu wera teitei mō te wā roa, me te tu atu i te pānga o ngā huringa pāmahana ohorere. Ahakoa i roto i ngā huringa makariri me te wera maha, ka taea te pupuri i te hanganga tika, ā, kāore e pakaru wawe, ka tautoko tonu, ka pumau hoki te oumu.
Tuarua, nā tōna kaha kawe kawenga pai rawa atu ka taea e ia te kawe tonu i ngā kawenga taumaha. Mā te hanganga o roto o te oumu me te kaha kawe kawenga o ngā rauemi ka puta he pēhanga kawenga tonu ki runga i ngā pou. Ko ngā pou rauemi noa e mau ana i ngā kawenga taumaha mō te wā roa ka piko, ka whati, me ētahi atu raruraru, ka pā kino ki te mahi noa o te oumu. He pakeke rawa te rauemi silicon carbide, he matotoru te hanganga, ā, he kaha miihini nui atu i ngā rauemi uku me te konganuku noa. Ka taea e ia te kawe ngāwari i ngā kawenga rerekē i roto i te oumu, ā, ahakoa i raro i te pāmahana teitei me te taiao kawenga taumaha mō te wā roa, ka taea e ia te pupuri i te āhua pumau me te karo i ngā tūponotanga hanganga i puta mai i te korenga o te kaha kawe.
Hei tāpiritanga, mā te ātete pai ki te waikura ka taea hoki e ngā pou oumu silicon carbide te urutau ki ngā āhuatanga mahi uaua ake. I roto i te tukanga whakaputa oumu i roto i ētahi ahumahi, ka puta he hau waikura, he puehu rānei kei roto he waikawa me te kawakore. Ko ngā pou rauemi noa e pāngia ana e ēnei pāpāho mō te wā roa ka waikura haere, ka heke te kaha me te poto o te ora ratonga. He pumau ngā āhuatanga matū o te silicon carbide, ā, ka taea e ia te ātete ki te mimiti o ngā pāpāho waikura pēnei i te waikawa me te kawakore. Ahakoa i roto i ngā taiao waikura kino, ka taea e ia te pupuri i te mahi pumau me te kore e whakakapi pinepine, ka whakaiti i ngā utu tiaki taputapu mō ngā umanga.
Mō ngā umanga, he hononga tika te mahi pumau o ngā oumu ki te whai huatanga o te whakaputa me te whakahaere utu, ā, he mea nui te whiriwhiri i tētahi pou oumu pono. Me ō rātou painga maha o te ātete ki te pāmahana teitei, te ātete ki te ru wera, te kaha ki te kawe kawenga, me te ātete ki te waikura, ka tino tutuki ngā whakaritenga nui o ngā oumu ahumahi i ngā pou oumu hiraka. Ka taea e rātou te whakarite kia haumaru te whakahaere o ngā oumu, te whakaroa i te roanga o te mahi a ngā taputapu, te whakaiti i te auau tiaki, ā, ka noho hei tautoko kounga teitei mō ngā umanga ki te whakapai ake i te pumau o te whakaputa.
I te pikinga ake o te hiahia mō te pono me te pakari o ngā taputapu i roto i te hanga ahumahi, kei te whānui haere tonu hoki ngā whakamahinga o ngā rauemi silicon carbide. Ā, ka noho tonu ngā pou o ngā oumu silicon carbide hei "pou matua", hei tautoko pakari mō ngā oumu ahumahi pāmahana-tiketike, hei āwhina i ngā umanga ki te whakatutuki i te hanga me te mahi whai hua me te pumau.
