Ụlọ ọrụ anyị na-enye ọrụ usoro mkpuchi SiC site na usoro CVD n'elu graphite, ceramics na ihe ndị ọzọ, nke mere na gas pụrụ iche nwere carbon na silicon na-emeghachi omume na okpomọkụ dị elu iji nweta mkpụrụ ndụ SiC dị ọcha, ụmụ irighiri ihe ndị a na-edebe n'elu ihe ndị a na-ekpuchi, na-akpụ oyi akwa mkpuchi SIC.
Isi atụmatụ:
1. Nguzogide oxidation dị elu:
Nguzogide oxidation ka dị ezigbo mma mgbe okpomọkụ dị elu dị ka 1600 C.
2. Nnukwu ịdị ọcha: nke a na-eme site na ntinye ikuku kemịkalụ n'okpuru ọnọdụ chlorination dị elu.
3. Nguzogide nbibi: elu ike, kọmpat elu, ezigbo ahụ.
4. Nguzogide corrosion: acid, alkali, nnu na organic reagents.
