Pereti Ukume Alumina Whakahōputu-Nui mō ngā Taputapu Ārahi me ngā Taputapu Ahumahi
E hanga ana a St.Cera i ngā pereti uku whakatakotoranga-rahi mai i te 99.8% alumina parakore-teitei (Al₂O₃) me ngā rahinga mōrahi tae atu ki te 1500mm te roa me te 600mm te whānui. Ka tutuki i ā mātou āheinga huri tika te papatahi o te 0.003mm i runga i te 100mm me te whakarara o te 0.002mm, kia rite ai te kounga o te mata mō ngā tono wāhi-rahi. Ka tae ki te matotoru tae atu ki te 100mm, ka tae ki te Ra0.1 te mutunga o te mata. Ka mahi ēnei pereti hei turanga pūwero korehau, hei pereti whakamahana, hei panera whakamahana hiko, me ngā papa rūma tukatuka i roto i te hanga haurua-ira, whakaaturanga, me te hanga photovoltaic. Kei te wātea ngā poka-roto, ngā poka-whakatau, me te whakaahua taha.
