Silicon nitride ndi ceramic yotuwa yokhala ndi kulimba kwambiri, kukana kutentha kwambiri, komanso zinthu zomwe sizingalowe muzitsulo zosungunuka.
Pogwiritsa ntchito mawonekedwewa, amagwiritsidwa ntchito pazigawo za injini zoyatsira mkati monga zida za injini yamagalimoto, ma nozzles a makina owotcherera a blowpipe, ndi zina, makamaka magawo omwe amayenera kugwiritsidwa ntchito m'malo ovuta monga kutenthedwa.
Ndi kukana kwake kuvala kwambiri komanso mphamvu zamakina apamwamba, kugwiritsa ntchito kwake ponyamula zida zodzigudubuza, mayendedwe ozungulira shaft ndi zida zopangira zida za semiconductor zikukulirakulira nthawi zonse.
