Litene tsa Si3N4-SiC

Sehlahisoa sena se qalile ho hlaha ho elella bofelong ba lilemo tsa bo-1960, 'me tšobotsi ea sona ke hore se sebelisa Si3N4 joalo ka setlamo. Si3N4 e teng pakeng tsa lijo-thollo tsa SiC ka mokhoa oa likristale tse bōpehileng joaloka nale kapa li-fibrous, 'me ke mofuta oa bohlokoa o mocha oa thepa ea refractory. Ka kakaretso e na le 70% ho 75% silicon carbide le 18% ho 25% silicon nitride. E na le khanyetso e ntle ea kutu, matla a flexural a 1400 ℃ a 50 ho isa ho 55MPa, le porosity e hlakileng ea 15%. Mocheso oa katoloso ea mocheso (4.5 ho 5.0) × 10-2℃-1. E lokiselitsoe ka mokhoa o phahameng oa mocheso oa sintering. E sebelisoa haholo bakeng sa blast furnace tuyere le aluminium electrolytic cell line. Lilemong tsa morao tjena, k'hamphani ea rona e sebelisitse litene tsa silicon nitride tse kopantsoeng tsa silicon carbide molomong oa sebōpi sa silicon ore le mokotla oa metsi oa silicon, o ntlafatsang haholo bophelo ba sebōpi le bophelo ba tšebeletso ea mokotla oa metsi oa silicon.
