Silicon Carbide Ceramic

Reaction Bonded Silicon Carbide

Zolemba zomangika za silicon carbide zidapangidwa kuti zikhale zolimba kwambiri komanso kukana dzimbiri. Ubwino wogwiritsa ntchito ma reaction bonded silicon carbide ndi awa: kukana kwapadera, kukhala ndi moyo wautali chifukwa cha kukana kwake kwa okosijeni, kukana kwambiri kugwedezeka kwamafuta, komanso mawonekedwe akulu kapena ang'onoang'ono ovuta.

Nitride Bonded Silicon Carbide

Silicon nitride yomangika silicon carbide idapangidwa kuti ikhale yolimba kwambiri. Itha kupangidwa m'mawonekedwe ovuta kwambiri chifukwa cha mawonekedwe ake otayidwa komanso imakhala ndi zotsutsana ndi mankhwala. Kugwiritsiridwa ntchito kwake kwakukulu kudzakhala komwe kukana kuvala kwapamwamba kumafunika kapena kumene mawonekedwe ndi ovuta kwambiri kuti apangidwe muzosakaniza zina. Matembenuzidwe othamangitsidwa kawiri omwe ali ndi porosity yocheperako komanso kukana kwa okosijeni bwino amapezekanso.

Sintered Silicon Carbide

Sintered alpha silicon carbide imapangidwa ndi sintering ultra-pure submicron powder. Ufawu umasakanizidwa ndi zothandizira zopanda oxide sintering, kenako zimapangidwira mawonekedwe ovuta ndi njira zosiyanasiyana ndikuphatikizidwa ndi sintering pa kutentha pamwamba pa 3632 ° F.

Njira yopangira sintering imapangitsa kuti pakhale silicon carbide yokhala ndi gawo limodzi lomwe ndi loyera kwambiri komanso lofanana, popanda porosity yomwe imalola zidazo kupirira malo owononga, malo owononga, ndi malo omwe akugwira ntchito pansi pa kutentha kwakukulu (2552 ° F). Izi zimapangitsa kuti sintered alpha silicon carbide ikhale yabwino pakugwiritsa ntchito monga mankhwala ndi slurry pampu zosindikizira ndi mayendedwe, ma nozzles, pampu ndi ma valve trim, mapepala ndi zida za nsalu, ndi zina zambiri.
