Lub tshuab hluav taws xob tau siv dav los ua cov khoom siv cua sov rau kev tua hluav taws. Ntxiv rau atmospheric siab sintering, piv txwv li pressureless sintering, muaj kub nias sintering thiab kub isostatic nias sintering. Txawm hais tias tsis tu ncua kub nias sintering nce cov zis, cov khoom siv thiab tuag yog siab dhau. Tsis tas li ntawd, vim axial cua sov, qhov ntev ntawm cov khoom raug txwv. Kub isostatic pressing sintering siv qhov kub thiab txias siab roj raws li kev hloov pauv nruab nrab, uas muaj qhov zoo ntawm cov cua kub sib txawv hauv txhua qhov kev qhia. Nws yog heev haum rau sintering ntawm cov khoom nrog complex duab. Vim tias cov qauv tsis sib xws, cov khoom siv yog 30 ~ 50% siab dua li cov xovxwm txias sintering. Nws yog 10-15% siab dua li ntawm kev kub nias sintering. Yog li ntawd, qee qhov khoom muaj nqis ntxiv alumina ceramic lossis cov khoom tshwj xeeb rau kev tiv thaiv hauv tebchaws thiab kev lag luam tub rog, xws li cov kabmob ceramic, iav, roj nuclear thiab phom phom, txais yuav kub isostatic nias firing txoj kev.
Qee qhov yuav tsum tau ua tiav tom qab sintering. Piv txwv li, cov khoom uas tuaj yeem siv los ua cov pob txha pob txha yuav tsum tau ua kom tiav qhov chaw siab, xws li daim iav, kom lubricity nce. Vim lub siab hardness ntawm cov khoom, nws xav tau ib tug nyuaj sib tsoo thiab polishing cib khoom rau xov. Xws li SiC, B4C lossis pob zeb diamond. Feem ntau, nws txais kev sib tsoo ib kauj ruam los ntawm ntxhib mus rau nplua abrasive, thiab qhov kawg saum npoo yog polished.

Txhawm rau ntxiv dag zog rau alumina ceramics thiab txhim kho lawv cov khoom siv dag zog, kev txhim kho tshiab ntawm alumina ceramics tau qhia txawv teb chaws. Cov txheej txheem yog tshiab thiab yooj yim. Txoj kev txhais tau tias tau txais yuav yog txheej txheej ntawm silicon compound zaj duab xis rau ntawm qhov chaw ntawm alumina ceramics los ntawm electron ray nqus tsev txheej, sputtering nqus txheej los yog tshuaj vapor evaporation, thiab kub nws ntawm 1200 ℃ ~ 1580 ℃ toughen alumina ceramics.
Lub zog ntawm cov khoom siv dag zog ntawm alumina ceramics tuaj yeem ua tau zoo heev ntawm cov hauv paus ntsiab lus kom tau txais alumina ceramics nrog lub zog.
