Isiseko sokusila samatye e-SIC sineempawu zokumelana nobushushu obuphezulu, ukumelana ne-oxidation, ukucoceka okuphezulu, i-asidi, i-alkali, ityuwa kunye ne-organic reagents, kunye nomsebenzi ozinzileyo womzimba kunye neekhemikhali. Xa kuthelekiswa negraphite yococeko oluphezulu, igraphite yokucoceka okuphezulu kwi-400 ℃ iqala i-oxidation enzulu, nokuba iqondo lobushushu alikho phezulu, ukusetyenziswa kwexesha elide kuya kuba ngenxa ye-oxidation kunye nomgubo, ngokuxhomekeke kwi-workpiece kunye netafile okanye ungcoliseko lokusetyenziswa kokusingqongileyo. , ngoko ke isiseko segraphite ye-SIC yokugquma njengesixhobo esitsha se-MOCVD, inkqubo ye-powder sintering ngokuthe ngcembe ithatha indawo yegraphite ecocekileyo.
Iimpawu eziphambili:
1. Ubushushu obuphezulu be-antioxidant: i-antioxidant, umsebenzi we-antioxidant usemhle kakhulu xa ubushushu buphezulu njenge-1600 ℃;
2. Ukucoceka okuphezulu: kufunyenwe ngendlela yokubeka umphunga wekhemikhali phantsi kobushushu obuphezulu be-chlorination;
3. Ukumelana nokhukuliseko: ubunzima obuphezulu, ubuso obuxineneyo, amasuntswana amahle;
Ukumelana nokubola: i-asidi, i-alkali, ityuwa kunye ne-organic reagents;
5. I-SIC surface layer yi-β-silicon carbide, i-cubic egxile ebusweni.
