Amatafari ya Si3N4-SiC

Iki gicuruzwa cyagaragaye bwa mbere mu mpera za za 1960, kandi ikiranga ni uko ikoresha Si3N4 nka binder. Si3N4 ibaho hagati yintete za SiC muburyo bwa inshinge zimeze nkurushinge cyangwa fibrous kristal, kandi ni ubwoko bushya bwibintu byangiritse. Mubusanzwe irimo karbide ya silicon 70% na 75% na nitride ya silicon 18% kugeza 25%. Ifite imbaraga zo kurwanya ruswa, 1400 strength imbaraga zidasanzwe za 50 kugeza 55MPa, kandi bigaragara ko ari 15%. Coefficient yo kwagura ubushyuhe (4.5 kugeza 5.0) × 10-2 ℃ -1. Byateguwe nuburyo bwo hejuru bwo gucumura. Ikoreshwa cyane cyane gutanura itanura tuyere na aluminium electrolytike selile. Mu myaka yashize, isosiyete yacu yakoresheje silicon nitride ihujwe na silicon karbide amatafari mumatafari ya silicon ore itanura yumunwa hamwe n umufuka wamazi wa silicon, ibyo bikaba biteza imbere cyane itanura nubuzima bwumufuka wamazi ya silicon.
