Izitena ze-Si3N4-SiC

Le mveliso yaqala ukuvela ekupheleni kweminyaka yoo-1960, kwaye uphawu lwayo kukuba isebenzisa iSi3N4 njengesibophelelo. I-Si3N4 ikhona phakathi kweenkozo ze-SiC ngendlela yeekristale ezenziwe ngenaliti okanye i-fibrous, kwaye luhlobo olutsha olubalulekileyo lwezinto eziphikisayo. Ngokuqhelekileyo iqulethe i-70% ukuya kwi-75% ye-silicon carbide kunye ne-18% ukuya kwi-25% ye-silicon nitride. Inokumelana ne-corrosion elungileyo, i-1400 ℃ amandla aguquguqukayo angama-50 ukuya kuma-55MPa, kunye ne-porosity ebonakalayo ye-15%. I-coefficient yokwandisa i-Thermal (4.5 ukuya ku-5.0) × 10-2℃-1. Ilungiswa ngendlela ye-sintering yobushushu obuphezulu. Isetyenziswa ikakhulu kwi-blast furnace tuyere kunye ne-aluminium electrolytic cell linening. Kwiminyaka yakutshanje, inkampani yethu isebenzise izitena ze-silicon nitride ezibotshelelwe kwi-silicon carbide emlonyeni we-silicon ore ore kunye nebhegi yamanzi ye-silicon, ephucula kakhulu ubomi beziko kunye nobomi benkonzo yebhegi yamanzi ye-silicon.
