I roto i te ao hanga ahumahi, kei te tuhi pakiwaitara hou ngā rauemi uku. Kāore i rite ki ngā oko uku i roto i te oranga o ia rā, kua whakaatu ngā uku ahumahi i tā rātou mahi tino pai i roto i ngā mara matua pēnei i te whakarewa, te miihini matū, me te pūngao hou. He āhuatanga motuhake tō te waikura konumohe, te nitride silicon, te waikura zirconium me ētahi atu rauemi, engari ina tae ki te kaha whānui tino kaha o te "kaitākaro katoa",ngā uku karāhe siliconko rātou tonu te hunga pai rawa atu.
He rite ngā uku alumina ki ngā tohunga toi tuku iho, e mōhiotia ana mō tō rātou pakeke me te utu iti, engari he ngāwari ki te hinga i ngā pāmahana tiketike. He tino pai te ātete o ngā uku silicon nitride ki ngā ru wera, pērā i ngā taputapu tika, engari tera pea he "rara ngohengohe" i roto i ētahi taiao waikura. He rite ngā uku zirconia ki ngā hōia ope motuhake, e mōhiotia ana mō tō rātou pakari rawa, engari tera pea ka "reti" wawe i roto i ngā pakanga pāmahana tiketike me te roa.
He rerekē, kua whakaatuhia e ngā uku silicon carbide he kaha whānui whakamiharo. Ko tēnei rauemi tioata, he mea hanga pūmau ki ngā ngota silicon waro, e toru ngā painga matua: ko tōna kawe wera tino kaha ka "marie" i roto i ngā taiao pāmahana teitei, ko tōna ātete pai ki te kakahu ka "toa ake" i roto i ngā āhuatanga mahi uaua, ā, ko tōna pumau matū ahurei he rite ki te whakangungu tiaki taiao, e ātete ana ki te whakaekenga mai o ngā momo pāpāho waikura.
I roto i te mara o te whakahaere wera, e toru ngā wā o te kawe wera o ngā uku silicon carbide i te maitai noa. Nā tēnei "pūkenga tohatoha wera" ā-roto, he mea pai mō ngā oumu pāmahana teitei me ngā papa haurua-ira. Ahakoa te wero o te pakaru me te haehae, ko tōna pakeke mata te tuarua o te taimana, e whakaatu ana i te roa o te ora ratonga i roto i ngā āhuatanga pēnei i ngā mīhini keri me ngā paipa kawe. Ko te mea tino onge ko te taea e tēnei rauemi te pupuri i tōna tae tūturu ahakoa i roto i ngā taiao waikura pēnei i ngā waikawa kaha, me te urutau pai ki ngā hiahia motuhake o ngā taputapu matū.
I te whanaketanga kaha o te umanga pūngao hou, kei te whakatuwherahia e ngā uku silicon carbide ngā rohe tono hou. I roto i te mara o te whakaputa hiko photovoltaic, ka noho hei rauemi tautoko pai rawa atu mō te ātete ki te huarere; i runga i te raina whakaputa pākahiko lithium, kua hurihia hei pereti sintered tino tika. Ko tēnei kaha "whiti-rohe" i ahu mai i tana huinga mahi ahurei - ka taea e ia te tu atu i ngā pāmahana teitei tonu o te 1350 ℃ me te mahi pumau i roto i ngā taiao tino makariri o te -60 ℃.
Hei tohunga hangarau e whai wāhi nui ana ki te ao o ngā uku silicon carbide, ka arotau tonu mātou i ngā hanganga rauemi me ngā tukanga sintering, me te pupuri tonu i ō mātou painga tuku iho, me te whakapai tonu i te kaha miihini me te tika o ngā āhuatanga o ngā rauemi. Mā te ōwehenga rauemi mata tika me te hangarau sintering auaha, kua tino pai ake te pono o ā mātou hua i raro i ngā āhuatanga mahi uaua, e whakarato ana i te taurangi rauemi pakari ake mō ngā taputapu ahumahi hou.
Ko te whiriwhiri i ngā rauemi uku ahumahi ko te rapu i te taurite i waenga i te mahi me te utu. Ko ngā uku karawiti silicon, me ō rātou painga utu-whai hua tino pai, kei te tautuhi anō i ngā paerewa o te whakaputa ahumahi - te whakaiti i te auau whakakapinga me te roa o te ora, te whakaiti i ngā utu tiaki me te mahi pumau ake, me te whakangawari i te whiriwhiri taputapu me te whānuitanga o ngā tono. Koinei pea te take matua e piki haere ana te tokomaha o ngā miihini e whakarārangi ana i tēnei hei rauemi pai.
Ina kōrero tātou mō te ahunga whakamua o te ahumahi, ko te auahatanga rauemi te mea tino taketake me te mea nui rawa atu. Ko te whanaketanga tonu o ngā uku silicon carbide ehara i te mea he ahunga whakamua noa iho i roto i te hangarau uku, engari he tohu anō hoki mō tētahi atu pikinga i roto i te whai huatanga o te whakaputa ahumahi. I tēnei wā o te whai i te mahi tino pai, kei te whakatuwherahia e tēnei rauemi uku "whakaaro" he wāhi auaha hou mō te hanga hou.
