Cov txheej txheem thev naus laus zis ntawm densifying granular ceramic lub cev thiab tsim cov khoom tawv yog hu ua sintering. Kev ua txhaum yog tshem cov voids ntawm cov khoom hauv lub cev, tshem tawm me me ntawm cov roj thiab lub cev tsis muaj zog ntawm cov organic, thiab ua kom cov qog loj tuaj thiab sib txuas ua ke los tsim cov tshuaj tshiab.
Lub qhov cub hluav taws xob feem ntau siv rau cov khoom siv cua sov siv rau kev tua hluav taws. Ntxiv nrog rau qhov ua haujlwm siab sintering, uas yog, tsis muaj lub siab ua txhaum, tseem muaj cov xovxwm kub sintering thiab kub isostatic nias. Txawm hais tias tas mus li kub nias sintering nce qib tawm los, cov nqi ntawm cov khoom siv thiab cov pwm yog siab dhau, thiab qhov ntev ntawm cov khoom lag luam tau txwv vim kub axial. Qhov kub isostatic nias siv qhov kub thiab qhov siab tshaj qhov pa roj raws li lub zog sib kis nruab nrab, thiab muaj qhov zoo ntawm cov cua kub tsis sib xws hauv txhua qhov kev qhia, thiab tsim nyog rau sintering ntawm cov duab puab. Vim tias cov qauv kev sib txawv, cov khoom siv cov khoom siv tau txhim kho los ntawm 30 txog 50% piv rau cov xovxwm txias sintering. Nws yog 10-15% siab tshaj li qhov kub tshaj plaws kub xovxwm sintering. Yog li no, qee qhov txiaj ntsig-ntxiv-nqi alumina ceramic khoom lossis qhov tshwj xeeb uas yuav tsum muaj rau kev tiv thaiv kev lag luam, xws li cov nplais roj iav, tsom iav, hluav taws xob nuclear thiab cov thoob ntim, thiab cov teb siv kub isostatic nias.
