Recon Carbider Carbide (RXsic, rescisi, stic, r-sic). Zinthu zoyambira ndi sinayi carbide. Palibe ntchito zothandizira zoimira zomwe zimagwiritsidwa ntchito. Zophatikizika zobiriwira zimatenthedwa mpaka 2200ºC kuti muphatikizidwe komaliza. Zomwe zimachitika zimakhala ndi 25% kwambiri, zomwe zimalepheretsa mphamvu zake; Komabe, zinthuzo zitha kukhala zoyera kwambiri. Njirayi ndiyothandiza kwambiri.
Kuchita ukapolo wa silicon carbide (rsic). Zoyambira zoyambira ndi sinayi carbide kuphatikiza kaboni. Gawo lobiriwira limalowetsedwa ndi silicon pamwamba pa 1450ºC ndi zomwe anachita: SIC + C + SI -> SIC. Microstructuctution nthawi zambiri imakhala ndi liricon yambiri yowonjezera, yomwe imalepheretsa chuma chake chotentha komanso kukana kutukuka. Kusintha pang'ono kumachitika pakuchitika; Komabe, sikicon ya silicon nthawi zambiri imapezeka padziko lonse lapansi. ZPC Rible amatengera ukadaulo wapamwamba, ndikupanga kuvala chovala, mbale, matayala, zigawo, zigawo zosanja, ma pivi, ndi zina zambiri.
Nitride womangidwa silicon carbide (NSBIC, Nsic). Zoyambitsa zoyambira ndi Sinayi Carbide kuphatikiza silicon ufa. Kanema wobiriwira wachotsedwa mdera la nayitrogen komwe kunachitika SIC + 3si + 2n2 - SIC + sic + sic + sic + SI3n4. Zinthu zomaliza zikuwonetsa kusintha pang'ono pokonzanso. Zinthuzo zikuwonetsa kuchuluka kwa mawonekedwe (nthawi zambiri pafupifupi 20%).
Mwachindunji silicon carbide (ssic). Silicon Carbide ndiye kuyambitsa zoyambira. Zogwiritsa ntchito zofalitsa ndi Boron kuphatikiza kaboni, ndipo kunenepa kumachitika ndi njira yokhazikika yokhazikika pamwambapa 2200ºC. Mphamvu zake zokutira ndi kukana kuphulika kumakhala kopambana chifukwa chakusowa kwa gawo lachiwiri lagalasi pa malire a tirigu.
Gawo lamadzimadzi limakuwutsani silican carbide (lessic). Silicon Carbide ndiye kuyambitsa zoyambira. Zothandizira Edzi ndi YNTRIOM Oxide kuphatikiza aluminiyumu. Kuphatikizika kumachitika pamwambapa 2100ºC ndi gawo lamadzimadzi ndikutsatira gawo lachiwiri lagalasi. Mphamvuyo nthawi zambiri imakhala yapamwamba kwambiri ndi ssic, koma malo otentha kwambiri ndipo kukana kwa kutukula sikuli bwino.
Hot Carkide Carbide (HPSIC). Silicon carbide ufa umagwiritsidwa ntchito ngati zoyambira. Zosintha zothandizira nthawi zambiri zimaphatikizira kaboni kapena yttrium oxide kuphatikiza aluminiyamu. Kuphatikizika kumachitika ndi gawo limodzi munthawi yomweyo kukakamizidwa kwamakina ndi kutentha mkati mwa graphite kumangopha. Mawonekedwe ndi mbale yosavuta. Kuchuluka kwa zinthu zosachimwa kumatha kugwiritsidwa ntchito. Makina katundu wa zinthu zotsekerera amagwiritsidwa ntchito ngati maziko a njira zina zofanizira. Magetsi katundu amatha kusinthidwa ndi kusintha mu edzi yopanga.
CVD silikicon carbide (cvduc). Izi zimapangidwa ndi mphamvu ya nthunzi ya mankhwala (CVD) yokhudza zomwe zimakhudza: ch3sicl3 -> a SIC + 3hcl. Zomwe zimachitika zimachitika pansi pa H2SPonse ndi SIC ikusungidwa ku graphite gawo lapansi. Njirayi imabweretsa zinthu zazitali kwambiri; Komabe, mbale zosavuta zokha zomwe zingapangidwe. Njirayi ndiyokwera kwambiri chifukwa cha kusamvana pang'onopang'ono.
Micy Vapor imapanga liwucon carbide (CVCSIC). Njirayi imayamba ndi yojambula yojambula yojambula yomwe imapangidwa mu mawonekedwe apakatikati pa graphite State. Njira yosinthira imawerengera gawo la graphite kupita ku satur olimba-boma kuti apange polycrystalline, shiichiometrical sic. Njira yoyendetsedwa mwamphamvu iyi imalola mapangidwe ovuta kuti apangidwe mu gawo lotembenuzidwa kwathunthu lomwe lakhala lolimba mtima komanso ungwiro wokwanira. Njira yosinthira ikufupikitsa nthawi yopanga ndikuchepetsa njira zina. * Kupatula komwe tadziwika): Ceradyne Insa
