Silicon nitride yog hmoov uas yog qhov nyuaj rau kev ua. Nws melts ntawm 1850 degree, thiab yog tias koj sim yaj nws ntawm qhov kub thiab txias saum toj no, nws tawg rau hauv silicon thiab nitrogen. Qhov no txhais tau tias nws yog qhov nyuaj rau siv cov tsoos kub xovxwm sintering tshuab. Txawm li cas los xij, ntxiv rau lwm cov tshuaj, xws li agglomerates lossis binders, tuaj yeem pab tuav silicon nitride hmoov ua ke. Cov txheej txheem no, hu ua kua-theem sintering, yuav siv qhov chaw nyob ntawm qhov kub tsawg dua thiab tsim cov khoom siv thaiv-zoo li.
Tab sis cov qauv no tuaj yeem qhia impurities rau cov khoom kawg vim tias nws cuam tshuam ntxiv ntawm kev sib txuas lus lossis cov neeg sawv cev sib ntxiv. Lwm txoj hauv kev uas tsim cov khoom huv huv yog hu ua enark mob ntshav sintering. Txoj kev siv hluav taws xob tsis zoo uas tau thov rau lub sijhawm luv luv (ob peb feeb). Txoj kev no ua rau compact thiab tuab silicon nitride block ntawm kub ntawm 1500-1700 degree.
