Ko ngā tukanga ahumahi pāmahana teitei e hiahia ana ki ngā rauemi e kaha ana ki te tu atu i te wera nui, te waikura, me te ru wera nui, me te kore e whakararu i te mahi.Ngā pereti ātete warowaihā silicon (SiC)he otinga tino pai, e tuku ana i te pakari me te whānui o ngā mahi puta noa i ngā rāngai matua. Mai i te mahi whakarewa ki ngā hikohiko me ngā uku, he mea nui ēnei pereti hei whakarei ake i te whai huatanga o te mahi, hei whakaiti i te wā kore mahi, hei whakanui ake i te kounga o te hua—he mea nui mō te hanga wera nui o ēnei rā.
Ko te mahi whakarewa tētahi o ngā wāhi matua e whakamahia ana mō ngā pereti ātete-waikawa silicon carbide. I roto i te whakarewa konumohe, te konutea, me te parahi, ka mahi ngā pereti hei arai, hei takotoranga, hei wāhanga tautoko hoki i roto i ngā oumu me ngā wāhi horoi. Nā tō rātou ātete tino pai ki te horo o te whakarewa rewa me te pāmahana teitei (tae atu ki te 1800°C) ka roa te ora o te mahi, ka whakaitihia te hiahia mō ngā whakakapinga auau. He rerekē ki ngā rauemi ātete-waikawa tuku iho, he pai hoki te kawe wera o ngā pereti SiC, e whakatairanga ana i te tohatoha wera ōrite e arotau ana i te pai o te rewa whakarewa me te whakaiti i te whakapaunga pūngao tae atu ki te 25%.
He nui te whakawhirinaki o te umanga hikohiko me te umanga haurua-ira ki ngā pereti ātete-waro silicon carbide mō ngā tukanga pāmahana-tiketike tino tika. I roto i te hanga o ngā haurua-ira, ngā LED, me ngā uku hiko, kāore e taea te tautohetohe i te whakahaere poke me te pumau o ngā āhuatanga. He tino pai ngā pereti ātete-waro SiC ki konei, nā te mea he koretake te matū, ā, ka mau tonu tō rātou āhua ahakoa i raro i ngā huringa whakamahana me te whakamatao. He whānuitia te whakamahinga i roto i te whakamahana wafer, te whakatakoto kohu matū (CVD), me te sintering o ngā wāhanga hiko, e āwhina ana i ngā kaihanga ki te whakaiti i ngā hapa me te whakanui ake i ngā reiti hua.
I roto i te rāngai uku me ngā taputapu horoi, kua hurihia te hanga e ngā pereti ātete waro silicon carbide. Ahakoa he porcelain sintering, he stoneware, he uku ahumahi rānei, ko te ātete pai o ngā pereti ki te ru wera ka ārai i te pakaru mai i ngā huringa pāmahana tere. Ka ātete hoki rātou ki te piri o te para me te glaze, ka noho ma tonu ngā mata, ka whakaiti i te wā tiaki. Ko ngā wheketere uku e whakamahi ana i ngā pereti ātete waro SiC e whakaatu ana i te roanga ratonga 3-5 ngā wā i whakaritea ki ngā pereti tikanga, me te whakapainga 10-15% i roto i ngā reiti tohu hua—he painga matua mō te hanga nui, he iti te utu.
I tua atu i ēnei rāngai matua, ka kitea ngā whakamahinga o ngā pereti ātete waro silicon carbide i roto i te pūngao whakahou me te rererangi. I roto i te hanga pākahiko lithium-ion, ka tautokohia e rātou te sintering pāmahana teitei o ngā rauemi cathode, kia rite ai ngā āhuatanga rauemi. I roto i te rererangi, ka whakamahia ēnei hei sinter i ngā wāhanga uku mahi-teitei mō ngā miihini me ngā avionics. Me ngā rahi me ngā whirihoranga ka taea te whakarite kia uru ki ngā hiahia taputapu kanorau, ka tukuna e ngā pereti ātete waro SiC te mahi pono e whakaritea ana ki ngā whakaritenga ahumahi motuhake.
Ko te haumi ki ngā pereti ātete waro silicon carbide ko te haumi ki te hiranga mahi mō te wā roa. Nā te huinga ahurei o te ātete wera, te ātete waikura, me te kawe wera, he mea pai hei whiringa utu-whai hua mō ngā ahumahi e whai ana ki te whakapai ake i te pumau me te hua. Whakapai ake i ō tukanga pāmahana teitei i tēnei rā me ngā pereti ātete waro silicon carbide—ko te wā e tūtaki ai te pakari ki te whai huatanga, ā, ko te pono ka ārahi i te angitu.
