Ubukorikori bwa sic ntabwo bufite imiterere yubukanishi gusa mubushyuhe bwicyumba, nkimbaraga zunamye cyane, kurwanya okiside nziza, kurwanya ruswa nziza, kwihanganira kwangirika kwinshi hamwe na coefficente nkeya, ariko kandi bifite imiterere yubukanishi bwiza mubushyuhe bwinshi (imbaraga, kurwanya creep, nibindi) mubikoresho bizwi bya ceramic. Gukanda cyane, gucumura bidashyushye, ibikoresho bya sinosti ya isostatike bishyushye, ikintu kinini kiranga karubide ya silicon ni imbaraga zubushyuhe bwo hejuru, ibikoresho bisanzwe bya ceramic kuri dogere 1200 ~ 1400 selisiyusi bizagabanuka cyane, na karuboni ya silikoni kuri dogere selisiyusi 1400 iracyabungabungwa kurwego rwo hejuru rwa 500 ~ 600MPa, bityo ubushyuhe bwakazi bushobora kugera kuri dogere selisiyusi 1600; Silicon karbide isahani yububiko bukomeye kandi bworoshye, coefficient yo kwaguka ni nto, ubukonje nubushyuhe, ntabwo byoroshye guhindura. Carbide ya silicon nubucucike buke, bityo ibice byubutaka bikozwe muri karubide ya silicon nibyo byoroshye.
Alumina ceramic ni ubwoko bwa alumina (Al2O3) nkumubiri nyamukuru wibikoresho bya ceramic, bikoreshwa muri firime yibyibushye. Ububiko bwa Alumina bufite ubushobozi bwiza, imbaraga za mashini hamwe nubushyuhe bwo hejuru. Twabibutsa ko gukaraba ultrasonic bisabwa. Kwambara kwayo gukubye inshuro 266 icyuma cya manganese ninshuro 171.5 zicyuma cya chromium nyinshi. Alumina ceramic nubwoko bwibikoresho byujuje ubuziranenge, bikoreshwa kenshi mugukora urupapuro rwabugenewe, rukora impeta nibindi bice. Ububiko bwa Alumina bushobora kwihanganira ubushyuhe bwo hejuru bugera kuri 1750 ℃ (alumina irenga 99%).
