dhoobada Sic ma aha oo kaliya inay leeyihiin sifooyin farsamo oo aad u fiican heerkulka qolka, sida xoog foorarsi sare leh, iska caabin oksaydh ah oo aad u fiican, iska caabbinta daxalka wanaagsan, caabbinta xidhashada sare iyo isku-dhafka hoose, laakiin sidoo kale waxay leeyihiin sifooyinka farsamada ugu fiican heerkulka sare (xoog, caabbinta gurguurta, iwm) oo ka mid ah alaabta dhoobada la yaqaan. Cadaadiska kulul ee cadaadiska, sintering non-cadaadiska, qalabka istaarijka kulul ee isostatic, dabeecadda ugu weyn ee silikoon carbide waa xoogga heerkulka sare, walxaha dhoobada caadiga ah ee 1200 ~ 1400 darajo Celsius si weyn ayaa loo dhimi doonaa, iyo silikoon carbide at 1400 darajo Celsius xoogga foorarsiga weli waxaa lagu hayaa heer sare oo ah 500 ~ 600MPa, markaa heerkulka shaqada wuxuu gaari karaa 1600 darajo Celsius; Silikon carbide texture texture adag oo jajaban, iskudarka ballaarinta waa yar yahay, qabow iyo iska caabin kulul, ma fududa in ay qallafsanaan. Silicon carbide waa cufan ugu yar, markaa qaybaha dhoobada ee ka samaysan silikoon carbide waa kuwa ugu fudud.
Alumina ceramic waa nooc ka mid ah alumina (Al2O3) oo ah jirka ugu weyn ee walxaha dhoobada ah, oo loo isticmaalo filim qaro weyn oo isku dhafan. ceramics Alumina waxay leeyihiin conductivity wanaagsan, xoog farsamo iyo iska caabin heerkul sare. Waa in la ogaadaa in loo baahan yahay dhaqidda ultrasonic. Xirashadu waa 266 jeer ka birta manganese iyo 171.5 jeer ka badan birta chromium-ka ah ee sarreeya. Alumina ceramic waa nooc ka mid ah alaab tayo sare leh, taas oo inta badan loo isticmaalo in lagu sameeyo xaashida daboolka dhoobada, giraanta dahaadhka iyo qaybo kale. Alumina ceramics waxay u adkeysan kartaa heerkulka sare ilaa 1750 ℃ (waxyaabaha aluminium ka badan 99%).
