Silicon Nitride Ceramic

Silicon nitride ceramics (Si3N4)

Silicon nitride ni ceramic yumukara ufite ubukana buvunitse cyane, guhangana nubushyuhe buhebuje, hamwe nibintu bitagereranywa byuma byashongeshejwe.

Ukoresheje ibyo biranga, bikoreshwa mubice bya moteri yaka imbere nkibice bya moteri yimodoka, imashini yo gusudira imashini zogosha, nibindi, cyane cyane ibice bigomba gukoreshwa mubidukikije nko gushyuha cyane.

Hamwe nimyenda myinshi yo kwihanganira imbaraga nubukanishi buhanitse, ikoreshwa ryayo mu gutwara ibice bya roller, ibyuma bizunguruka hamwe n’ibikoresho bitanga ibikoresho bya semiconductor bihora byiyongera.
