Siab tsis muaj sintered silicon carbide (SSIC)yog tsim los siv zoo heev SiC hmoov uas muaj sintering additives. Nws yog ua tiav siv cov txheej txheem tsim rau lwm cov ceramics thiab sintered ntawm 2,000 txog 2,200 ° C nyob rau hauv ib qho inert gas cua.As raws li zoo-grained versions, nrog grain loj <5 um, coarse-grained versions nrog grain loj txog li 1.5. mm muaj.
SSIC yog qhov txawv ntawm lub zog siab uas nyob ze rau qhov kub siab heev (kwv yees li 1,600 ° C), tswj lub zog ntawd ntev!
