Silicon nitride yog ib hom ceramic grey uas muaj zog tawg, tiv taus kub zoo heev, thiab cov khoom tsis yooj yim rau cov hlau yaj.
Siv cov yam ntxwv no, nws yog siv rau cov khoom siv sab hauv lub cav xws li lub cav tsheb, lub tshuab vuam tshuab blowpipe nozzles, thiab lwm yam, tshwj xeeb tshaj yog cov khoom uas yuav tsum tau siv rau hauv qhov chaw ib puag ncig hnyav xws li overheating.
Nrog nws txoj kev tiv taus siab thiab lub zog siab, nws daim ntawv thov hauv cov khoom siv bearing roller, rotating shaft bearings thiab cov khoom siv semiconductor ntau lawm spare qhov chaw txuas ntxiv nthuav dav.
