Ngā papa uku konumoheHe rauemi uku mahi-teitei te nuinga o te wā he mea hanga ki te waikura konumohe. He mea hanga ēnei mā roto i ngā tukanga whakamahana pāmahana-teitei. I runga i te nui o te alumina, ka whakarōpūtia ēnei ki ngā taumata parakore-iti (75%-85% Al₂O₃), parakore-waenga (96% Al₂O₃), me te parakore-teitei (≥99% Al₂O₃). He mea āhua rite ki te hanganga moroiti matotoru me ngā āhuatanga matū pumau, ā, he kaha miihini tino pai ēnei papa, he ātete pāmahana-teitei, he ārai hiko hoki. He whānuitia te whakamahinga hei rauemi tūāpapa i roto i ngā hikohiko, ngā pūnaha hiko, te rererangi, me ētahi atu ahumahi matatau.
Ngā Painga o ngā Papa Uku Alumina:
Ārai Hiko Tino Pai
Mā te ātete teitei (>10¹⁴ Ω·cm) me te pūmau dielectric iti (8-10), ka wehea pai e ngā uku alumina ngā iahiko hiko, ka ārai i te poto o te ara iahiko i roto i ngā taiao auau teitei, ngaohiko teitei rānei.
Te Awe Wera Teitei
Ko ngā papa raro he 96% te nui o te alumina, ā, ka taea te kawe wera o te 24-28 W/(m·K), e āhei ai te tohatoha wera pai mai i ngā wāhanga hiko hei ārai i te wera nui me te whakaroa i te roa o te ora o te taputapu.
Kaha Mīhini Tino Pai
Ko te kaha piko o te 300-400 MPa, me te pakeke teitei (te pakeke Mohs 9) me te ātete ki te kakahu, ka mau tonu i roto i ngā āhuatanga mahi uaua.
Pūmautanga Matū Kaha
He ātete ki ngā waikawa, ngā kawakore, te waikura, me te makuku, ka mau tonu te pumau o ngā papa alumina ahakoa i ngā pāmahana teitei (tae atu ki te 1600°C) i roto rānei i ngā taiao waikura.
Te Hanga Tika
Mā te miihini tika ka taea te maeneene o te mata taumata-micron, e tutuki ai ngā whakaritenga āhua tino pakari mō ngā tono pēnei i te takai haurua-ira.
