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.
Ngā Whakatakotoranga(i runga i te 99.8% Al₂O₃):
| Taonga | Uara |
| Rauemi | 99.8% Arumina (Ai) |
| Kiato | 3.93 karamu/cm³ |
| Kaha Whakapiko | 361 MPa |
| Te Pakari o te Whati | 3–4 MPa·m¹/² |
| Te Pakari o Vickers | 16 GPa |
| Te Tauwehenga o te Rangatahi | 380 GPa |
| Te Arahi Wera | 32 W/m·k |
| Te Whakawhanuitanga Wera (25-1000°C) | 7.2×10⁻⁶/℃ |
| Kaha Whakakorehiko | 15×10⁶ V/m |
| Ātete Motuhake | >10¹⁴ Ω·mm²/m |
| Te Mahana Whakahaere Mōrahi | 1600°C |
Ngā tono:
- · Matua whakamahana mō ngā tauhohenga epitaxial
- · Te arai me ngā pereti taupoki o te rūma plasma
- · Ngā ārai hiko ngaohiko teitei
- · Tūāpapa tūmau mō ngā karetao whakahaere wafer
Te Hanga:
Te pēhi isostatic → te miihini matomato → te sintering i te 1600°C → te huri CNC ki ngā rahinga whakamutunga (±0.01 mm te manawanui). Ka tirotirohia ia matua mā te CMM me te kimi hapa ultrasonic.
Te Whakapūmau Kounga:
Kua whakamanahia a ISO 9001:2015. Whakamātautau wero tae mō ngā kapiti mata; whakamātautau kaha dielectric e ai ki a ASTM D149.
Angā painga i runga i ētahi atu mea uku:
- · He kaha ake te kaha o te dielectric i te zirconia (15 vs <10×10⁶ V/m)
- · He iti ake te utu i te SiC mō ngā tono kore-plasma
- · He ātete matū tino pai ki ngā halogens (haunga te HF)
Ngā Āhua Ritenga:
He rango, he pae tapawhā, he pereti, he āhuahanga uaua rānei. Ko te rahi o te āhuatanga he 0.5 mm te iti rawa.
