Ehara i te mea he pai noa ngā āhuatanga miihini o ngā uku Sic i te pāmahana rūma, pērā i te kaha piko teitei, te ātete waikura pai, te ātete waikura pai, te ātete kakahu teitei me te tauwehenga waku iti, engari he pai hoki ngā āhuatanga miihini i te pāmahana teitei (kaha, ātete ngoki, me ētahi atu) i roto i ngā rauemi uku e mōhiotia ana. Ko te sintering pēhi wera, te sintering kore-pēhi, te sintering pēhi isostatic wera, ko te āhuatanga nui o te silicon carbide ko te kaha pāmahana teitei, ka tino heke te kaha o te rauemi uku noa i te 1200 ~ 1400 nekehanga Celsius, ā, ko te kaha piko o te silicon carbide i te 1400 nekehanga Celsius ka mau tonu i te taumata teitei ake o te 500 ~ 600MPa, nō reira ka taea e te pāmahana mahi te eke ki te 1600 nekehanga Celsius; He pakeke, he pakarukaru te kakano o te pereti silicon carbide, he iti te tauwehenga whānui, he ātete makariri me te wera, kāore e ngāwari ki te huri. Ko te silicon carbide te mea iti rawa te matotoru, nō reira ko ngā wāhanga uku i hangaia ki te silicon carbide te mea mama rawa.
Ko te uku alumina he momo alumina (Al2O3) te tinana matua o te rauemi uku, e whakamahia ana i roto i ngā ara iahiko whakauru kiriata matotoru. He pai te kawe hiko o ngā uku alumina, he kaha miihini, he ātete pāmahana teitei. Me mōhio ko te horoi ultrasonic te mea e hiahiatia ana. Ko tōna ātete kakahu he 266 ngā wā i te maitai manganese, ā, he 171.5 ngā wā i te rino maka chromium teitei. Ko te uku alumina he momo rauemi whakamarumaru kounga teitei, e whakamahia ana hei hanga pepa whakamarumaru uku, mowhiti whakamarumaru me ētahi atu wāhanga. Ka taea e ngā uku alumina te tu atu i te pāmahana teitei tae atu ki te 1750℃ (neke atu i te 99% te ihirangi alumina).
