Isi seramiiki Alumina dị ọcha nke ukwuu maka ihe ndị na-enye semiconductor
E ji usoro seramiiki alumina nke St.Cera mee ihe nke ọma site na 99.8% Al₂O₃ dị elu, na-enye ike dielectric pụrụ iche (15×10⁶ V/m), nkwụsi ike okpomọkụ ruo 1600°C, na iguzogide ịrị elu n'okpuru ibu. A na-eji isi ndị a eme ihe dị ka ihe owuwu na ihe ndozi okpomọkụ dị elu, ntọala ihe na-ekpo ọkụ, ihe mkpuchi ụlọ plasma, na ihe mkpuchi eletriki. Ike siri ike nke ihe ahụ (16 GPa) na obere nnabata mmiri (0%) na-eme ka a nwee ntụkwasị obi ogologo oge na gburugburu ebe siri ike.
Nkọwapụta(dabere na 99.8% Al₂O₃):
| Akụ na ụba | Uru |
| ihe | 99.8% Alumina (Ivory) |
| Njupụta | 3.93 g/cm³ |
| Ike nke Flexural | 361 MPa |
| Ike Mgbaji | 3–4 MPa·m¹/² |
| Ike Vickers | 16 GPA |
| Modulu nke Young | 380 GPA |
| Ọgbakọ okpomọkụ | 32 W/m·k |
| Mgbasawanye Okpomọkụ (25-1000°C) | 7.2 × 10⁻⁶/℃ |
| Ike Dielectric | 15 × 10⁶ V/m |
| Nguzogide Pụrụ Iche | >10¹⁴ Ω·mm²/m |
| Oke okpomọkụ ọrụ kachasị | 1600°C |
Ngwa:
- · Isi ihe na-ekpo ọkụ maka ihe na-eme ka ...arụ ọrụ nke ọma
- · Ihe mkpuchi na efere mkpuchi nke ụlọ plasma
- · Ihe mkpuchi eletriki dị elu
- · Ntọala ihe eji arụ ọrụ maka robot ndị na-eji wafer arụ ọrụ
Mmepụta:
Isostatic pressing → green machining → sintering na 1600°C → CNC grinding ruo na nha ikpeazụ (±0.01 mm ndidi). A na-enyocha isi nke ọ bụla site na CMM na nchọpụta ntụpọ ultrasonic.
Ntụkwasị obi ịdị mma:
Asambodo ISO 9001: 2015. Nnwale agba maka mgbawa elu; nnwale ike dielectric dịka ASTM D149 si dị.
AUru dị elu karịa seramiiki ndị ọzọ:
- · Ike dielectric dị elu karịa zirconia (15 vs <10×10⁶ V/m)
- · Ọnụ ego dị ala karịa SiC maka ngwa ndị na-abụghị plasma
- · Ọ na-eguzogide kemịkalụ dị mma megide halogens (ma e wezụga HF)
Ụdị omenala:
Silinda, ogwe anọ, efere, ma ọ bụ geometri dị mgbagwoju anya. Nha njirimara kacha nta bụ 0.5 mm.
Kpọtụrụ anyị maka atụmatụ isi omenala na nkwado ihe nlereanya okpomọkụ.
