Ngongo Arataki Uku Tika mō te Hononga Waea me te Āpiti Mate
He mea hanga te ngongo arataki uku a St.Cera mai i te 99.5% alumina, zirconia rānei kua whakapūmautia ki te yttria, e whakarato ana i te ātete kakahu teitei me te poka o roto maeneene (Ra ≤0.2 μm). He wāhanga nui ēnei ngongo i roto i ngā hononga waea, ngā mīhini whakapiri mate, me ngā taputapu tiki-me-whakanoho, ngā waea hononga arataki, ngā capillaries, ngā pūwero korehau rānei me te iti o te waku me te kore poke matūriki.

Matua Ukume Alumina Parakore-Teitei mō ngā Taputapu Ārahi-Haupapa
He tino tika te hanga o te matua uku alumina a St.Cera mai i te 99.8% Al₂O₃ tino parakore, e tuku ana i te kaha hiko tino pai (15×10⁶ V/m), te pumau wera tae atu ki te 1600°C, me te ātete ngoki i raro i te kawenga. Ka whakamahia ēnei matua hei wāhanga hanganga i roto i ngā taputapu tukatuka pāmahana teitei, ngā turanga whakamahana, ngā arai rūma plasma, me ngā ārai hiko. Ko te pakeke teitei o te rauemi (16 GPa) me te iti o te mimiti wai (0%) ka whakarite i te pono mō te wā roa i roto i ngā taiao uaua.

Pūwero Korehau Paerewa e Hangai Ana ki te Arumina – Te Pakari Teitei mō te Mīhini Tika
He mea hanga tēnei pūwero korehau i ahu mai i te alumina mai i te 99.8% Al₂O₃, e tuku ana i tētahi mata maeneene kāore he pore me ngā tauira awaawa korehau ritenga. Ka whakarato i te pakari tino pai (te modulus a Young 380 GPa) me te papatahi (≤3 μm), he mea tino pai mō te huri tika, te whakapiri, me te tapatapahi i ngā papa haurua-ira me ngā wāhanga whatu. Mā te kawe wera teitei o te rauemi (32 W/m·k) ka whakarite kia ōrite te pāmahana i te wā e tukatukahia ana.

ST.CERA Kua Whakaritea mō te Mowhiti Ukume Alumina me te Kōpae Ukume
I hangaia mā te pēhi matao isostatic, ā, i whakakorikoria i raro i te pāmahana teitei, kātahi ka mīhinihia me te orohia kia tika, ka taea e ngā wāhanga e toe ana o te uku te whakatutuki i ngā whakaritenga tino pakari o ngā taputapu haurua-ā-ira me ōna āhuatanga o te ātete ki te kakahu, te ātete ki te waikura, te iti o te horapa wera, me te whakamarumaru. Ka taea e ngā uku te mahi i roto i ngā momo taputapu whakaputa haurua-ā-ira maha me ngā āhuatanga pāmahana teitei, korehau, hau waikura rānei mō te wā roa.
He mea hanga mai i te paura alumina tino parakore, ka tukatukahia mā te pēhi matao isostatic, te sintering pāmahana teitei me te whakaotinga tika, ka taea te eke ki te ātete ine ki te ±0.001 mm, te mutunga mata Ra 0.1, te ātete pāmahana 1600℃.
