Silicon nitride ndeye grey ceramic ine yakakwira kuputsika kusimba, yakanakisa kupisa kutyisa kuramba, uye zvisingapindike zvivakwa kune simbi dzakanyungudutswa.
Uchishandisa hunhu uhwu, inoiswa kune emukati mejini injini sezvikamu zvemotokari, welding muchina blowpipe nozzles, nezvimwewo, kunyanya zvikamu zvinoda kushandiswa munzvimbo dzakaoma sekupisa.
Nekupokana kwayo kwepamusoro uye kusimba kwemagetsi, mashandisirwo ayo mukutakura zvikamu zvemaroller, inotenderera shaft mabhengi uye semiconductor yekugadzira michina yekugadzira masipire ari kuramba achiwedzera.
