Degreasing, debinding
Ntxiv nrog rau kev siv tshuab moulding raws li kev nias kom qhuav, cov khoom tsim los ntawm lwm cov txheej txheem yuav tsum tau ua kom qis thiab debinding ua ntej yuav sintered hauv lub cub tawg, vim tias lwm cov txheej txheem uas tsis yog qhuav nias yuav ntxiv qee feem ntawm zirconium hmoov thaum molding. Cov yas yas, cov yas yas no yuav tsum tau muab tshem tawm tom qab cov khoom tsim tawm, txwv tsis pub nws yuav muaj qhov cuam tshuam zoo rau cov khoom siv sintered. Cov yas yas feem ntau yog tsim los ntawm siv quav ciab paraffin thiab lwm yam khoom siv polymer. Cov ntaub ntawv no yuav tsum tau ua kom pom cov yas zoo thiab ua kom sov ntawm qhov kub thiab txias, thiab qee qhov tawv thiab lub zog ntawm chav sov.
Sintering
Cov txheej txheem sintering muaj rau zirconia ceramics feem ntau suav nrog: ⑴ siab tsis siv neeg sintering, ⑵ kub nias sintering thiab reactive kub nias sintering, ⑶hot isostatic nias (HIP), ⑷microwave sintering, ⑸ultra-siab siab sintering, ⑹spark ntshav sintering (SPS), ⑺In-situ compression molding thiab sintering, thiab lwm yam.
