Ibice bya Ceramic bya Alumina Ceramic bifite isuku nyinshi bikoreshwa mu nganda n'ibikoresho bya semiconductors
St.Cera ikora ibice bya alumina (Al₂O₃) bya keramike hakurikijwe ibisabwa n'umukiriya. Ikoresheje alumina ifite 99.8% by'ubuziranenge buhanitse, ibi bice bitanga imbaraga nziza zo kuzunguruka (361 MPa), ubukana bwinshi (16 GPa), n'imbaraga nziza za dielectric (15 × 10⁶ V/m). Byagenewe ibikoresho bya semiconductor, ibikoresho bidashobora kwangirika, ibyuma bikingira amashanyarazi, n'ibikoresho bikoresha ubushyuhe bwinshi, ibi bikoresho bitanga amazi hafi ya zero (0%) n'ubushyuhe bungana na 7.2 × 10⁻⁶/℃, bitanga ubuziranenge buhamye mu gihe cy'ibihe bikomeye.
Ibisobanuro(hashingiwe kuri 99.8% Al₂O₃):
Umutungo | Agaciro |

| Ubucucike | 3.93 g/cm³ |
| Imbaraga zo Kongera Uburemere | 361 MPa |
| Gukomera kw'imvune | 3–4 MPa·m¹/² |
| Ubukomere bwa Vickers | 16 GPa |
| Modulus ya Young | 380 GPa |
| Ubushobozi bwo gutwara ubushyuhe | 32 W/m·k |
| Kwaguka k'ubushyuhe (25–1000°C) | 7.2×10⁻⁶/℃ |
| Dielectric Constant | 9.6 |
| Inguni yo Gutakaza Dielectric | 0.0001 |
| Imbaraga za Dielectric | 15×10⁶ V/m |
| Ubudahangarwa bwihariye | >10¹⁴ Ω·cm |
| Ubushyuhe ntarengwa bwo gukora | 1600°C |
Porogaramu:
- · Utwuma dutunganya ibyuma bya semiconductor, aho abantu bareba, n'aho bakwirakwiza gazi
- · Ibikoresho biramba, impeta zifunga, n'imipira yo guterura
- · Ibikoresho bikingira amashanyarazi bifite ingufu nyinshi n'ibikingira amashanyarazi bitanga ingufu
- · Ibikoresho by'ifuru, ibikoresho bifasha mu gushyushya, n'imiyoboro yo kurinda thermocouple
Uburyo bwo gukora:
Gukanda Isostatic → imashini y'icyatsi kibisi → gusya kuri 1600°C → Gusya neza / gusya kuri CNC → Gusukura hakoreshejwe ikoranabuhanga → Igenzura rya CMM 100%. Imiterere y'ijimetero, inkuta nto (≥0.5 mm), n'ubushobozi bwo kwihanganira ibintu (kugeza kuri ± 0.01 mm) bigerwaho buri gihe.
Igenzura ry'Ubuziranenge:
Icyemezo cya ISO 9001:2015. Buri gice gipimwa imbaraga zo kuzunguruka (guhindagurika kw'ingingo 3), ubukana (Vickers), imbaraga za dielectric (ASTM D149), no kudashyuha cyane (10 cycles, 25°C ↔ 1000°C). Nta mvune cyangwa uduce tugaragara munsi ya mikorosikope ya 20×.
Ibyiza ugereranyije n'ibice by'icyuma cyangwa polimeri:
- · 3–5× ikomeye kurusha icyuma kidashonga (16 GPa ugereranije na ~2 GPa)
- · Idafite imiti — irwanya aside, alkali, na halojeni (usibye HF)
- · Imashini ikingira amashanyarazi >10¹⁴ Ω·cm, ituma ikoreshwa mu bidukikije bifite amashanyarazi menshi
- · Serivisi ihoraho kugeza kuri 1600°C, irenga kure imipaka y'ibyuma cyangwa pulasitiki
Guhindura:
Twemera ibishushanyo by'abakiriya (mu buryo bwa STEP/IGS) kandi dutanga prototyping yihuse (ibyumweru 2-3). Ibice bishobora gutangwa nk'ibitonyanga, ibisugutiwe, bivanze, cyangwa bisukuye (Ra ≤0.05 μm). Hari uburyo bwo kuzunguruka impande, imiyoboro ihuza imigozi, imyobo ikoze mu ikoranabuhanga, n'imiyoboro idafite umwuka.
Icyitonderwa: Ku bijyanye n'ibikoresho bisaba gukomera cyane kw'ivunika, tekereza ku bice bya zirconia (ZrO₂). Kugira ngo ubone ubushobozi bwo gutwara ubushyuhe bwinshi, reba ibicuruzwa byacu bya BeO cyangwa Si₃N₄. Amakuru yose ari hejuru akurikiza neza imbonerahamwe y'imiterere ya Al₂O₃ yatanzwe (urwego rwa 99.8%).
