Chuck faakiyuum Alumina ah oo loogu talagalay jarjarista saxda ah iyo shiidi
Qalabka faakiyuumka ee alumina ee St.Cera waxaa laga sameeyay 99.8% nadiifnimo sare oo Al₂O₃ ah oo leh godad faakiyuum oo sax ah oo lagu farsameeyay mashiinka faakiyuumka. Awooddeenna shiididda saxda ah waxay gaartaa fidsanaan 0.003mm iyo barbardhigid 0.002mm ah, taasoo hubinaysa in si fiican loo hagaajiyo wafer-ka inta lagu jiro jarista, shiidida gadaal, iyo kormeerka. Maaddadu waxay bixisaa xoog dabacsanaan sare (361 MPa), adkaansho (16 GPa), iyo xasillooni kuleyl ilaa 800°C. Waxaa laga heli karaa qaabab wareegsan oo gaaraya 600mm dhexroorka dibadda (OD) iyo qaabab leydi ah ilaa 1500mm dherer. Godadka faakiyuumka waxaa loo qaabeeyey si gaar ah (qaababka isku xiran, radial, ama shabagga) si ay ugu habboonaadaan shuruudaha habka gaarka ah. Qalabka kasta waxaa lagu hubiyaa laysarka interferometer waxaana la siiyaa warbixin xaqiijin ah oo fidsan.
