Mowhiti Ukume Alumina Tika mō te Hiri, te Whakamarumaru me te Whakapiri
He mea hanga tika te mowhiti uku a St.Cera mai i te 99.8% alumina parakore-teitei (Al₂O₃) mō ngā tono e hiahia ana ki te ātete kakahu teitei, te whakamarumaru hiko, me te pumau wera tae atu ki te 1600°C. Ka tautokohia e ā mātou āheinga hanga he diameter o waho tae atu ki te 600mm, he matotoru tae atu ki te 100mm, me ngā diameter o roto he iti noa iho ki te 0.2mm, me te papatahi o te 0.003mm, te whakarara o te 0.002mm, me te porowhita o te 0.01mm. Kei te wātea hei mowhiti hiri, mowhiti mokowā, mowhiti pupuri, ngā kōtaha ritenga rānei. Nā te kore porowhita me te koretake o te matū o te rauemi, he pai mō ngā taiao matū me te plasma kaha.
