Isisekelo sokugaya itshe esimbozwe yi-SIC sinezici zokumelana nokushisa okuphezulu, ukumelana nokushiswa kwe-oxidation, ubumsulwa obuphezulu, i-acid, i-alkali, usawoti kanye nama-reagent e-organic, kanye nomsebenzi ozinzile womzimba namakhemikhali. Uma kuqhathaniswa ne-graphite ehlanzekile ephezulu, i-graphite ehlanzekile ephezulu ku-400℃ iqala ukushiswa okukhulu, noma ngabe izinga lokushisa aliphezulu, ukusetshenziswa kwesikhathi eside kuzobangelwa ukushiswa kwe-oxidation kanye ne-powder, kuncike endaweni yokusebenza kanye netafula noma ukungcola kokusetshenziswa kwemvelo, ngakho-ke isisekelo se-graphite yokumboza ye-SIC njengemishini emisha ye-MOCVD, inqubo yokusila i-powder kancane kancane ithatha indawo ye-graphite ehlanzekile ephezulu.
Izici eziyinhloko:
1. I-antioxidant yokushisa okuphezulu: i-antioxidant, umsebenzi we-antioxidant usemuhle kakhulu lapho izinga lokushisa lifinyelela ku-1600℃;
2. Ubumsulwa obuphezulu: obutholakala ngendlela yokufakwa komphunga wamakhemikhali ngaphansi kwesimo sokushisa okuphezulu kwe-chlorination;
3. Ukumelana nokuguguleka: ubulukhuni obuphezulu, ubuso obuminyene, izinhlayiya ezincane;
Ukumelana nokugqwala: i-asidi, i-alkali, usawoti kanye nama-reagent e-organic;
5. Ingqimba yobuso be-SIC yi-β-silicon carbide, i-cubic egxile ebusweni.
