Ibisobanuro
Isosiyete yacu itanga serivise zo gutunganya SiC hakoreshejwe uburyo bwa CVD hejuru ya grafite, ceramique nibindi bikoresho, kugirango imyuka idasanzwe irimo karubone na silikoni ikora ubushyuhe bwinshi kugirango ibone molekile nziza ya SiC, molekile zashyizwe hejuru yibikoresho bisize, gukora urwego rwo kurinda SIC.
Ibyingenzi
1. Kurwanya ubushyuhe bwo hejuru bwa okiside: kurwanya okiside iracyari byiza cyane mugihe ubushyuhe buri hejuru ya 1600 C.
2. Isuku ryinshi: bikozwe nubumara bwa chimique munsi yubushyuhe bwo hejuru bwa chlorine.
3. Kurwanya isuri: gukomera kwinshi, hejuru yuzuye, ibice byiza.
4. Kurwanya ruswa: aside, alkali, umunyu na reagent.
