Agakoresho ko mu bwoko bwa Alumina gafite imyenge yo gukoresha mu gutunganya umugati muke
Agace k'imyobo gakozwe muri alumina ka St.Cera gakozwe muri Al₂O₃ ifite 99.6% y'ubuziranenge buhanitse, gafite imyenge ifunguye ya 30–45%, kandi gafite ingano imwe y'imyobo iri hagati ya 10 na 50 μm. Bitandukanye n'uduce tw'imyobo, ubuso bw'imyobo butanga icyuho gikwirakwira inyuma ya wafer yose, bikuraho ibimenyetso by'inkombe kandi bigafasha gufata buhoro uduce tworoheje cyane (≤100 μm) cyangwa uduce tw'imyobo dupfundikiye. Ibikoresho bitanga imbaraga zo kuzunguruka za ≥250 MPa no kudahungabana k'ubushyuhe kugeza kuri 400°C mu kirere.
Ibisobanuro(hashingiwe kuri 99.6% Al₂O₃):
| Umutungo | Agaciro |
| Ibikoresho | 99.6% Alumina (Yera) |
| Ubwinshi bw'amabara | 30–45% (ishobora guhindurwa) |
| Ingano y'Umwobo Uciriritse | 10–50 μm |
| Imbaraga zo Kongera Uburemere | ≥250 MPa |
| Ubucucike | 3.88 g/cm³ |
| Ubugari (burenga mm 200) | ≤5 μm |
| Ubushyuhe Bunini bwo Gukora | 400°C (umwuka) |
| Kurangiza ubuso | Ifite imirasire irenga (Ra ≤0.8 μm) |
Porogaramu:
- · Agace gato k'umugati (≤50 μm) gasya inyuma
- · Gushyiraho wafer igoramye yo gukata
- · Gutoragura die mu buryo bwihariye
- · Gukoresha ikirahure mu buryo bwa substrate
Inganda:
Ifu ivanze n'udupira tw'imyenge → gukanda isostatic → gusya kuri 1600°C → gufunga kugeza ku bunini bwa nyuma. Buri gapfunyika kapimirwa uburyo bwo gusohora amazi mu buryo bungana (guhindagurika k'umuvuduko <5%) kandi kagasuzumwa kugira ngo harebwe uko udupira dukwirakwira (SEM).
Ibyiza ugereranije n'udupira dusanzwe:
- · Nta gusiga ikimenyetso ku ruhande rw'inyuma cyangwa guhinduranya imashini
- · Ifata uduce tw'inyama twambaye umugozi dufite ubunini bugera kuri 500 μm
- · Ahantu ho kwisukura (imyenge irinda kuziba)
- · Inkunga isanzwe ikuraho stress zo mu gace runaka
Cgukoresha uburyo bwo kwifashisha:
Imiterere y'uruziga cyangwa kare, umurambararo wa mm 100–450. Impeta yo gufunga impande irahari kugira ngo igenzurwe n'ahantu hatandukanye.
Saba icyitegererezo cy'ingano ya wafer yawe.
