Silicon Carbide Ceramics ndi Silicon Nitride Ceramics

Chidule chaSilicon Carbide Ceramics
Silicon carbide ceramics ndi mtundu watsopano wa zinthu zadothi zopangidwa makamaka kuchokera ku silicon carbide ufa kudzera mu sintering yotentha kwambiri. Zoumba za silicon carbide zimakhala ndi kuuma kwakukulu, kukana kusavala, kukana kwa dzimbiri, komanso kukana kutentha kwambiri, zokhala ndi makina abwino kwambiri, matenthedwe, komanso magetsi. Zoumba za silicon carbide zitha kugawidwa m'magulu opangidwa ndi sintered silicon carbide ceramics ndi reaction sintered silicon carbide ceramics chifukwa cha njira zosiyanasiyana zowombera.

Zambiri za Silicon Nitride Ceramics
Silicon nitride ceramics ndi chinthu chofunikira kwambiri chochita bwino kwambiri cha ceramic. Ili ndi zida zabwino zamakina, kukana kutentha kwambiri, kukana kwa dzimbiri, komanso matenthedwe amafuta. Poyerekeza ndi silicon carbide ceramics, silicon nitride ceramics ndi yokhazikika. Zoumba za silicon nitride zimakhala ndi kuuma kwambiri ndi mphamvu, motero zimagwiritsidwa ntchito kwambiri popanga mafakitale ndi makina olondola pansi pa kutentha ndi kupanikizika.
Kusiyana pakati pa silicon carbide ceramics ndi silicon nitride ceramics
1. Zomangamanga zosiyanasiyana
Mapangidwe a silicon carbide ceramics amapangidwa ndi mphamvu yomangirira pakati pa njere za silicon carbide, pomwe kapangidwe ka silicon nitride ceramics amapangidwa ndi silicon nitrogen bond yopangidwa ndi silicon ndi maatomu a nayitrogeni. Chifukwa chake, zoumba za silicon nitride ndizokhazikika kuposa zoumba za silicon carbide.
2. Ntchito zosiyanasiyana
Silicon carbide ceramics amagwiritsidwa ntchito kwambiri m'malo opangira kutentha kwapamwamba, monga zomangira za ng'anjo yotenthetsera, mazenera owonera m'mafakitale a semiconductor, ndi malo opangira makina. Silicon nitride ceramics amagwiritsidwa ntchito kwambiri podula, kugaya, kutchinjiriza magetsi, chitetezo ndi madera ena pansi pa kutentha kwambiri komanso kupanikizika kwambiri pamakampani opanga.
3. Ntchito zosiyanasiyana
Zoumba za silicon carbide zimakhala ndi kutentha kwapamwamba, zosavala, komanso zosagwirizana ndi dzimbiri, pomwe zoumba za silicon nitride sizingokhala ndi kutentha kwambiri, zosavala, komanso zolimbana ndi dzimbiri, komanso kukhathamiritsa kwamafuta komanso kutsekemera kwamagetsi, kotero kuti zitha kugwiritsidwa ntchito m'magawo ambiri.
Mwachidule, ngakhale zitsulo zonse za silicon carbide ceramics ndi silicon nitride ceramics ndizopangidwa ndi zida za ceramic zogwira ntchito kwambiri, mapangidwe awo, ntchito, ndi katundu wawo ndi wosiyana. Ogwiritsa ntchito ayenera kusankha zida zoyenera malinga ndi zosowa zawo.
