High-Purity Alumina Ceramic Core yeSemiconductor Fixtures
St.Cera's alumina ceramic core yakagadzirwa ne99.8% high-purity Al₂O₃, ichipa simba re dielectric rakanaka (15×10⁶ V/m), kugadzikana kwekupisa kusvika 1600°C, uye kuramba kukwira pasi pemutoro. Macore aya anoshandiswa sezvikamu zvechimiro muzvishandiso zvekupisa zvakanyanya, ma heater bases, plasma chamber liners, uye electrical insulators. Kuomarara kwakanyanya kwechinhu ichi (16 GPa) uye kunyura kwemvura shoma (0%) zvinoita kuti chigare kwenguva refu munzvimbo dzakaoma.
Magadzirirwo(zvakavakirwa pa99.8% Al₂O₃):
| Pfuma | Kukosha |
| Zvinhu | 99.8% Alumina (Nyanga dzenzou) |
| Kuwanda kwevanhu | 3.93 g/cm³ |
| Simba reKuchinjika | 361 MPa |
| Kusimba Kwekutyoka | 3–4 MPa·m¹/² |
| Kuomarara kwaVickers | 16 GPa |
| Modulus yeYoung | 380 GPa |
| Kufambisa kwekupisa | 32 W/m·k |
| Kuwedzera kwekupisa (25-1000°C) | 7.2×10⁻⁶/℃ |
| Simba reDielectric | 15×10⁶ V/m |
| Kuramba Kwakananga | >10¹⁴ Ω·mm²/m |
| Tembiricha Yekushanda Yakanyanya | 1600°C |
Mashandisirwo:
- · Chinofukidza hita yemagetsi epitaxial reactors
- · Plasma chamber liner nemaplate ekufukidza
- · Zvidziviriri zvemagetsi zvine simba guru
- · Nzvimbo yekugadzira marobhoti ekubata wafer
Kugadzira:
Kudzvanya kweIsostatic → green machining → sintering pa1600°C → CNC grinding kusvika pachiyero chekupedzisira (± 0.01 mm tolerance). Chikamu chimwe nechimwe chinoongororwa neCMM uye ultrasonic flaw detection.
Kuvimbisa Hunhu Hwakanaka:
Chitupa cheISO 9001:2015. Kuongororwa kwedhayi inopinza muvhu kuti ione kana paine mitswe pamusoro; bvunzo yesimba re dielectric zvichienderana neASTM D149.
Amabhenefiti pane mamwe maceramics:
- · Simba re dielectric rakakwirira kupfuura zirconia (15 vs <10×10⁶ V/m)
- · Mutengo wakaderera pane SiC kune vasiri kushandisa plasma
- · Kudzivirira zvakanyanya makemikari kuhalogens (kunze kweHF)
Maumbirwo Akagadzirwa Nemunhu:
Masirinda, mativi akaenzana, maplate, kana jiometri dzakaoma. Saizi shoma yechinhu ingava 0.5 mm.
Tibatei kuti muwane magadzirirwo emukati akagadzirwa nemaoko enyu uye rutsigiro rwekutevedzera thermal.
