Isisekelo sokugaya amatshe enziwe nge-SIC sinezici zokumelana nokushisa okuphezulu, ukumelana ne-oxidation, ukuhlanzeka okuphezulu, i-asidi, i-alkali, usawoti kanye nama-organic reagents, kanye nokusebenza okuzinzile ngokomzimba namakhemikhali. Uma kuqhathaniswa nokuhlanzeka okuphezulu kwe-graphite, i-graphite ephezulu yokuhlanzeka ku-400 ℃ iqala i-oxidation enamandla, ngisho noma izinga lokushisa lingephezulu, isicelo sesikhathi eside sizoba ngenxa ye-oxidation kanye nempushana, sithembele ku-workpiece netafula noma ukungcoliswa kokusetshenziswa kwemvelo, ngakho-ke isisekelo se-SIC sokuhlanganisa i-graphite njengesisekelo esisha se-MOCVD inqubo ye-powder kancane kancane, esikhundleni se-sinterity powder
Izici eziyinhloko:
1. Ukushisa okuphezulu kwe-antioxidant: i-antioxidant, umsebenzi we-antioxidant usemuhle kakhulu lapho izinga lokushisa liphezulu njenge-1600 ℃;
2. Ukuhlanzeka okuphezulu: kutholwe ngendlela yokubeka umhwamuko wamakhemikhali ngaphansi kwesimo sokushisa okuphezulu kwe-chlorination;
3. Ukumelana nokuguguleka: ubulukhuni obukhulu, indawo eminyene, izinhlayiya ezinhle;
Ukumelana nokugqwala: i-asidi, i-alkali, usawoti kanye nama-organic reagents;
5. I-SIC surface layer yi-β-silicon carbide, i-cubic egxile ebusweni.
