Silicon Nitride Ceramic

Silicon nitride ceramics (Si3N4)

Silikon nitride waa dhoobo cawl leh oo leh jab adag oo jaban, iska caabin shoog kulayl oo aad u fiican, iyo sifooyin aan la dabooli karin oo biraha dhalaalay.

Iyada oo la adeegsanayo sifooyinkan, waxaa lagu dabaqaa qaybaha matoorka gubashada gudaha sida qaybaha mishiinka baabuurta, mishiinka alxanka ee tuubooyinka, iwm, gaar ahaan qaybaha u baahan in loo isticmaalo jawi adag sida kulaylka.

Iyada oo ay iska caabbinta xirashada sare iyo xoogga farsamada sare, codsiyadeeda ee qaybaha rullaluistemadka, wareegyada usheeda dhexe iyo qalabka wax soo saarka semiconductor qaybo si joogto ah u fidin.
