Porcelain ya silikoni ikoze mu buryo bwa reaction-sintered carbide ifite imbaraga nziza zo gukanda ku bushyuhe bw'ikirere, irwanya ubushyuhe ku mwuka ushyushye, irwanya kwangirika neza, irwanya ubushyuhe neza, igabanya ubushyuhe buhoro, igabanya ubushyuhe bwinshi, irwanya ubushyuhe bwinshi, irwanya ubushyuhe kandi ikangiza, irinda inkongi n'ibindi bintu byiza. Ikoreshwa cyane mu binyabiziga, ikoresha ikoranabuhanga mu buryo bwikora, kurengera ibidukikije, ubwubatsi bw'indege, ibikoresho by'ikoranabuhanga, ingufu z'amashanyarazi n'ibindi, yabaye ibumba ry'imiterere rihendutse kandi ridashobora gusimburwa mu nganda nyinshi.
Gucukura bidakoresha umuvuduko bizwi nk'uburyo bwiza bwo gucukura SiC. Ku mashini zitandukanye zicukura zikomeza, gucukura bidakoresheje umuvuduko bishobora kugabanywamo gucukura mu buryo bufatika no gucukura mu buryo buhanitse. Mu kongeramo B na C bikwiye (umwuka uri munsi ya 2%) hamwe mu ifu nziza cyane ya Beta SiC, S. Proehazka icukurwa mu mubiri wa SIC ufite ubucucike burenze 98% muri 2020, hamwe na Al2O3 na Y2O3 nk'inyongera. Icukura 0.5m-SiC munsi ya 1850-1950 (ubuso bw'uduce dufite SiO2 nto), umwanzuro ni uko ubucucike bwa porcelain ya SiC burenze 95% by'ubucucike bw'ibanze bw'ibitekerezo, ingano y'ingano ni nto, kandi ingano mpuzandengo ni nini, ni ukuvuga 1.5μm.
Karubide ya silikoni ikora neza ivuga inzira yose yo kugaragaza imiterere y’ibice bifite imyenge hamwe n’igice cy’amazi cyangwa igice cy’amazi gifite imikorere myiza, kunoza ubwiza bwa billet, kugabanya umwobo w’imyobo, no gukaranga umusaruro urangiye ku buryo bufatika kandi bungana. Ifu ya Plutonium-sic na grafiti ifite isuku nyinshi bivangwa mu rugero runaka bigashyushya kugeza hafi muri 1650 kugira ngo hakorwe intanga y’umusatsi. Muri icyo gihe, yinjira cyangwa yinjira mu cyuma binyuze mu gice cy’amazi cya Si, igahinduka na karubide ya silikoni kugira ngo ikore plutonium-sic, kandi igahuza n’uduce twa plutonium-sic turiho. Nyuma yo kwinjira muri Si, umubiri urimo gukora ibintu bifite ubucucike burambuye n’ingano idafunze ushobora kuboneka. Ugereranyije n’ubundi buryo bwo gukora ibintu, mu gihe cyo gukora ibintu bifite ubucucike bwinshi, ingano ya sintering ni nto, ishobora gukora ingano ikwiye y’ibicuruzwa, ariko hari SiC nyinshi ku mubiri ufite calcium, imiterere y’ubushyuhe bwinshi bwa SiC porcelain ikora ibintu izaba mbi kurushaho. Ibumba rya SiC ridafite umuvuduko wa calcium, ibumba rya SiC rishyushye rya calcium rikozwe muri isostatic hamwe n’ibumba rya SiC rikozwe muri reaction sintered bifite imiterere itandukanye.
Abakora karubide ya silikoni ikora ibintu bishyushye: Urugero, porcelain ya SiC ku rwego rw'ubucucike bwa calcined relative relative n'imbaraga zo gupfunyika, gupfunyika gushyushye no gupfunyika gushyushye bya isostatic ni benshi, naho SiC ikora ibintu bishyushye ni nkeya. Muri icyo gihe, imiterere ya porcelain ya SiC irahinduka iyo ihinduye uburyo bwo gupfunyika. Gupfunyika gushyushya no gupfunyika bishyushye no gupfunyika kwa SiC bifite ubudahangarwa bwiza bwa alkaline n'ubudahangarwa bwa aside, ariko porcelain ya SiC ifite ubudahangarwa buke kuri HF n'izindi aside corruption zikomeye cyane. Iyo ubushyuhe buri munsi ya 900, imbaraga zo gupfunyika za porcelain nyinshi za SiC ziba nyinshi cyane kuruta iza porcelain ikora ibintu bishyushye cyane, kandi imbaraga zo gupfunyika za porcelain ya SiC ikora ibintu bishyushye zigabanuka cyane iyo zirenze 1400. (Ibi biterwa no kugabanuka gutunguranye kw'imbaraga zo gupfunyika kw'ingano runaka ya Si ikirahure cya laminated kirenze ubushyuhe runaka mu mubiri wa calcined. Imikorere y'ubushyuhe bwinshi bwa SiC ceramics ikora ibintu bishyushye nta gupfunyika no munsi y'ubushyuhe buhoraho bushyushye cyane bigira ingaruka ku bwoko bw'inyongera.
