High-Purity Alumina Ceramic Core ya Zokonza za Semiconductor
Chitsulo cha alumina cha St.Cera chimapangidwa ndi 99.8% ya Al₂O₃ yoyera kwambiri, yomwe imapereka mphamvu ya dielectric yapamwamba kwambiri (15×10⁶ V/m), kukhazikika kwa kutentha mpaka 1600°C, komanso kukana kugwedezeka pansi pa katundu. Zitsulozi zimagwiritsidwa ntchito ngati zida zomangira mu zida zotenthetsera kutentha kwambiri, maziko a heater, ma plasma chamber liners, ndi ma insulators amagetsi. Kulimba kwa chipangizochi (16 GPa) komanso kuyamwa madzi pang'ono (0%) kumatsimikizira kudalirika kwa nthawi yayitali m'malo ovuta.
Mafotokozedwe(kutengera 99.8% Al₂O₃):
| Katundu | Mtengo |
| Zinthu Zofunika | 99.8% Alumina (Minyanga ya Njovu) |
| Kuchulukana | 3.93 g/cm³ |
| Mphamvu Yosinthasintha | 361 MPa |
| Kulimba kwa Kusweka | 3–4 MPa·m¹/² |
| Kuuma kwa Vickers | 16 GPa |
| Modulus ya Achinyamata | 380 GPa |
| Kutentha kwa Matenthedwe | 32 W/m·k |
| Kuwonjezeka kwa Kutentha (25-1000°C) | 7.2×10⁻⁶/℃ |
| Mphamvu ya Dielectric | 15×10⁶ V/m |
| Kukana Kwapadera | >10¹⁴ Ω·mm²/m |
| Kutentha Kwambiri Kogwira Ntchito | 1600°C |
Mapulogalamu:
- · Chotenthetsera chapakati cha ma reactor a epitaxial
- · Chophimba chipinda cha plasma ndi mbale zophimba
- · Zotetezera magetsi zamagetsi zamphamvu
- · Malo oyambira opangira ma robot ogwiritsira ntchito wafer
Kupanga:
Kukanikiza kwa isostatic → makina obiriwira → kupukuta pa 1600°C → Kupukuta kwa CNC mpaka miyeso yomaliza (± 0.01 mm tolerance). Pakati pa chinthu chilichonse pamafunika kufufuzidwa pogwiritsa ntchito CMM ndi ultrasound detection.
Chitsimikizo chadongosolo:
Chitsimikizo cha ISO 9001:2015. Kuyesa kolowera utoto wa ming'alu pamwamba; kuyesa mphamvu ya dielectric motsatira ASTM D149.
Aubwino kuposa zoumba zina:
- · Mphamvu ya dielectric yapamwamba kuposa zirconia (15 vs <10×10⁶ V/m)
- · Mtengo wotsika kuposa SiC pa ntchito zopanda plasma
- · Kukana bwino mankhwala ku ma halojeni (kupatula HF)
Maonekedwe Opangidwa Mwamakonda:
Masilinda, mipiringidzo ya sikweya, mbale, kapena ma geometri ovuta. Kukula kwa mawonekedwe osachepera 0.5 mm.
Lumikizanani nafe kuti mupeze mapangidwe apadera apakati ndi chithandizo choyesera kutentha.
