Isahani ya Ceramic ya Alumina ifite isuku nyinshi – yo gukingira no gushyiramo ubushyuhe bwinshi
Isahani ya St.Cera ikozwe muri alumina ya 99.8% ifite ubwiza bwinshi (Al₂O₃), itanga imbaraga nyinshi za dielectric (15×10⁶ V/m), ubushyuhe buhamye kugeza kuri 1600°C, kandi irwanya kwangirika neza. Isahani zikozwe neza kugira ngo zigere ku bugari bwa ≤5 μm hejuru ya mm 100 n'ubugari bwa Ra ≤0.4 μm. Iboneka mu bugari busanzwe kuva kuri mm 1 kugeza kuri mm 20, ingano zihariye kugeza kuri mm 500×500. Ikoreshwa nk'ibikoresho bikingira amashanyarazi, ibikoresho bishyushya, imiyoboro y'ibyumba, n'ibikoresho bigabanya ubushyuhe.
Ibisobanuro (bishingiye kuri 99.8% Al₂O₃):
| Umutungo | Agaciro |
| Ibikoresho | 99.8% Alumina (Amahembe y'inzovu) |
| Ubucucike | 3.93 g/cm³ |
| Imbaraga zo Kongera Uburemere | 361 MPa |
| Imbaraga za Dielectric | 15×10⁶ V/m |
| Ubudahangarwa bwihariye | >10¹⁴ Ω·mm²/m |
| Ubushobozi bwo gutwara ubushyuhe | 32 W/m·k |
| Kwaguka k'ubushyuhe (25-1000°C) | 7.2×10⁻⁶/℃ |
| Ubushyuhe Bunini bwo Gukora | 1600°C |
| Ubugari (kuri mm 100) | ≤5 μm |
| Kwihanganira ubunini | ± 0.05 mm |
| Ubukana bw'ubuso | Ra ≤0.4 μm |
Porogaramu:
- · Ibyuma bikingira amashanyarazi mu bikoresho bifite ingufu nyinshi
- · Amasahani yo gushyigikira amashanyarazi mu itanura rikwirakwira
- · Imiyoboro y'icyumba cyo kuraramo ya CVD/PVD
- · Amasahani y'ibanze yo gukoresha mu gukaraba amacupa y'umwuka
Ibyiza:
- · 0% by'amazi anyurwamo – nta myuka isohoka mu cyuma gifunze
- · Idakora imiti – irwanya aside na halogen (usibye HF)
Guhindura:
Umwobo, ibice biciwe, impande zizunguruka, no gushyiramo ibyuma birahari.
