5. Sintering

Lub cev ntsuab qhuav yog raug kub hnyiab hauv qhov chaw tswj tau. Cov txheej txheem sintering ua rau cov khoom siv ceramic sib txuas ua ke, ua rau muaj qhov ntom ntom ntom ntom ntom ntom ntom.

6. Machining (yeem)

Tom qab sintering, lub substrate tej zaum yuav dhau mus ntxiv machining txheej txheem xws li sib tsoo, polishing, los yog txiav kom ua tiav qhov ntev thiab nto tiav.

Daim ntawv thov
