Pereti Ukume Alumina Parakore-Teitei – mō te Ārai me ngā Tauira Pāmahana-Teitei
He mea hanga te pereti uku a St.Cera mai i te 99.8% alumina parakore-teitei (Al₂O₃), e tuku ana i te kaha hiko-kore teitei (15×10⁶ V/m), te pumau wera tae atu ki te 1600°C, me te ātete kakahu tino pai. He tino tika te whiri o ngā pereti kia eke ki te papatahi ≤5 μm neke atu i te 100 mm me te taratara o te mata Ra ≤0.4 μm. E wātea ana i roto i ngā matotoru paerewa mai i te 1 mm ki te 20 mm, ngā rahi ritenga tae atu ki te 500×500 mm. Whakamahia hei ārai hiko, hei turanga whakamahana, hei arai rūma, me ngā papa korehau.

Ngā tono:
- · Ngā pereti whakamahana hiko i roto i ngā taputapu ngaohiko teitei
- · Ngā pereti tautoko whakamahana i roto i ngā oumu horapa
- · Ngā arai rūma mō te CVD/PVD
- · Ngā pereti turanga mō ngā pūwero korehau
Ngā Painga:
- · 0% mimiti wai – kāore he hau e puta ana i roto i te korehau
- · Kāore e ngoikore te matū – ātete ki ngā waikawa me ngā halogen (haunga te HF)
Whakaritenga:
Kei te wātea ngā kōhao, ngā tapahi, te whakaawhiwhi taha, me te whakarewa.
