Silicon carbide porcelain falcelinta-sitered waxay leedahay xoog cadaadis wanaagsan oo heerkul ah, iska caabin kulaylka hawada oksaydhka, caabbinta xidhashada wanaagsan, iska caabbinta kulaylka wanaagsan, isu-dheellitirka yar ee fidinta tooska ah, isku-xidhka wareejinta kulaylka sare, qallafsanaanta sare, caabbinta kulaylka iyo burburinta, ka hortagga dabka iyo sifooyinka kale ee tayada sare leh. Si weyn loogu isticmaalo baabuurta, farsamaynta farsamada, ilaalinta deegaanka deegaanka, injineernimada hawada hawada, agabka elektiroonigga ah ee ku jira macluumaadka, tamarta korantada iyo qaybaha kale, waxay noqdeen dhoobada qaab-dhismeed kharash-ku-ool ah oo aan la bedeli karin meelo badan oo warshado ah.
Cadaadis la'aanta waxaa loo yaqaanaa habka calcination ee SiC. Mashiinnada tuurista joogtada ah ee kala duwan, sintering-free-saxaafadeed waxaa loo qaybin karaa calcination wejiga adag iyo calcination wajiga dareeraha waxqabadka sare. Marka lagu daro B iyo C ku habboon (content oxygen in ka yar 2%) si wada jir ah oo aad u fiican budada Beta SiC, S. Proehazka waxaa lagu daraa jirka SIC calcined leh cufnaanta qaraabo ka badan 98% at 2020, oo leh Al2O3 iyo Y2O3 sida lagu daro. Calcined 0.5m-SiC ee hoos yimaada 1850-1950 (oogada walxaha leh SiO2 yar), gabagabada ayaa ah in cufnaanta SiC porcelain ay dhaafto 95% cufnaanta aragtida aasaasiga ah, cabbirka hadhuudhku waa yar yahay, cabbirkuna waa weyn yahay, taas oo ah 1.5μm.
Silikoon carbide falcelinta falcelintu waxa ay tilmaamaysaa habka oo dhan ee ka tarjumaya qaab dhismeedka daloolka leh oo leh weji dareere ah ama waji dareere ah oo waxqabadkiisu sarreeyo, hagaajinta tayada biilka, yaraynta daloolka hawo-mareenka, iyo xisaabinta badeecada dhammaatay oo leh awood gaar ah iyo saxnaan cabbireed. Budada Plutonium-sic iyo garaafka saafiga ah ee sarreeya ayaa lagu qasi karaa qayb gaar ah waxaana lagu kululeeyaa ilaa 1650 si loo soo saaro embriyaha timaha. Isla mar ahaantaana, waxay dhex gashaa ama dhex gelisaa birta iyada oo loo marayo wajiga dareeraha Si, waxay ka tarjumaysaa silikoon carbide si ay u sameyso plutonium-sic, waxayna ku xirtaa qaybo plutonium-sic ah. Ka dib dhexgalka Si, falcelinta jidhka oo sinteed leh oo faahfaahsan cufnaanta qaraabada iyo cabbirka aan baakadaysan ayaa la heli karaa. Marka la barbardhigo hababka kale ee sintering, in habka of falcelinta cuf sare sintering size transformation waa yara yar, waxay abuuri kartaa cabbirka saxda ah ee alaabta, laakiin waxaa jira wax badan oo SiC on jidhka calcined, sifooyinka heerkulka sare ee falcelinta sintered SiC porcelain noqon doonaa ka sii daran. ceramics-ka SiC-ga ee aan cadaadiska lahayn, ceramics-ka SiC-ga leh ee kulul iyo ceramics-ka fal-celinta SiC-ga ayaa leh astaamo kala duwan.
Soosaarayaasha silikoon carbide ee falcelinta falcelisa: Tusaale ahaan, SiC porcelain oo ah heerka cufnaanta qaraabada la kariyey iyo xoogga foorarsiga, cadaadis cadaadis kulul iyo cadaadis cadaadis istatic ah ayaa badan, iyo falcelinta falcelinta SiC waa mid hooseeya. Isla mar ahaantaana, sifooyinka jireed ee SiC porcelain waxay beddelaan isbeddelka beddelka calcination. Sintering-ka aan cadaadis lahayn, sintering saxaafadda kulul iyo falcelinta falcelinta ee SiC porcelain leeyihiin iska caabin alkaline wanaagsan iyo caabbinta aashitada, laakiin falcelinta sintered SiC porcelain leeyahay iska caabin daciif ah HF iyo kale oo aad u xoog badan daxal acid. Marka heerkulka deegaanku uu ka yar yahay 900, xoogga foorarsiga ee inta badan SiC porcelain aad ayuu uga sarreeyaa tan heerkulka sare ee porcelain sintered, iyo xoogga foorarsiga ee sintered SiC porcelain fal-celin si xoog leh hoos u dhaco marka ay dhaafto 1400. sinteed aan cadaadis calcination iyo cadaadis joogto ah oo kulul ayaa inta badan saameeya noocyada lagu daro.
