Silicon carbide porcelain falcelinta-sitered waxay leedahay xoog cadaadis wanaagsan oo heerkulka deegaanka ah, iska caabin kulaylka hawada oksaydhka, caabbinta xidhashada wanaagsan, iska caabinta kulaylka wanaagsan, iskudar yar ee ballaarinta tooska ah, isku xidhka kulaylka sareeyo, engegnaanta sare, iska caabinta 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 (content oksijiin ka yar 2%) si wadajir ah budada Beta SiC oo aad u fiican, S. Proehazka waxaa lagu daraa jirka SIC oo leh cufnaanta qaraabada ah ee ka badan 98% ee 2020, oo leh Al2O3 iyo Y2O3 sida wax 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, celceliska cabbirkuna waa weyn yahay, kaas oo waa 1.5 μm.
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 barbar dhigo hababka kale ee sintering, in habka of falcelinta cuf sare sintering size beddelka waa yara yar, waxay abuuri kartaa size saxda ah ee alaabta, laakiin waxaa jira wax badan oo SiC on jidhka calcined, sifooyinka heerkulka sare ee falcelinta sintered SiC porcelain. ayaa ka sii dari doona. 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 inta badan SiC porcelain aad ayuu uga sarreeyaa tan heerkulka sare ee foornada sintered, iyo xoogga foorarsiga ee sintered SiC porcelain fal-celin aad u hoos u dhaco marka ay dhaafto 1400. (Tani waxaa keena lama filaan ah. hoos u dhaca xoogga foorarsiga ee qadar go'an oo galaas dahaaran Si ka baxsan heerkul gaar ah oo ka mid ah heerkulka jidhka ee sarreeya sinteed aan cadaadis calcination iyo cadaadis joogto ah oo kulul ayaa inta badan saameeya noocyada lagu daro.
