Dhoobada Sic ma laha oo keliya sifooyin farsamo oo heer sare ah heerkulka qolka, sida xoogga foorarsiga sare, iska caabin oksaydh oo aad u fiican, iska caabin wanaagsan oo daxal ah, iska caabin sare oo xirasho iyo isku-dhafka is-jiidjiid hooseeya, laakiin sidoo kale waxay leeyihiin sifooyinka farsamada ugu fiican heerkulka sare (xoogga, iska caabinta gurguurta, iwm.) oo ka mid ah walxaha dhoobada ee la yaqaan. Sintering-ka kulul ee riixitaanka, sintering-ka aan riixin, walxaha sintering-ka ee kulul ee isostatic-ka ah, astaamaha ugu weyn ee sintering-ka silikoon waa xoogga heerkulka sare, walxaha dhoobada caadiga ah ee xoogga 1200 ~ 1400 digrii Celsius ayaa si weyn loo dhimi doonaa, iyo silicon carbide-ka oo ah xoogga foorarsiga 1400 digrii Celsius ayaa weli lagu hayaa heer sare oo ah 500 ~ 600MPa, sidaa darteed heerkulka shaqadu wuxuu gaari karaa 1600 digrii Celsius; Qaabka saxanka silikoon carbide waa mid adag oo jilicsan, isku-darka ballaarinta waa mid yar, iska caabin qabow iyo kulul, ma fududa in la beddelo. Silicon carbide waa kan ugu cufan, sidaa darteed qaybaha dhoobada ah ee laga sameeyay silikoon carbide ayaa ah kuwa ugu fudud.
Dhoobada Alumina waa nooc ka mid ah alumina (Al2O3) oo ah jirka ugu weyn ee walxaha dhoobada ah, oo loo isticmaalo wareegyada isku dhafan ee filimada qaro weyn. Dhoobada Alumina waxay leeyihiin gudbin wanaagsan, xoog farsamo iyo iska caabin heerkul sare. Waa in la ogaadaa in loo baahan yahay dhaqidda ultrasonic. Iska caabbinta xirashadeedu waa 266 jeer ka badan birta manganese iyo 171.5 jeer ka badan birta chromium ee sare. Dhoobada Alumina waa nooc ka mid ah walxaha dahaarka leh ee tayo sare leh, kaas oo inta badan loo isticmaalo in lagu sameeyo xaashida dahaarka dhoobada ah, giraanta dahaarka leh iyo qaybo kale. Dhoobada Alumina waxay u adkeysan kartaa heerkulka sare ilaa 1750℃ (ka kooban aluminium in ka badan 99%).
