Ku isoko, tumenyereye cyane ibikoresho byihariye bya ceramic: karbide ya silicon, alumina, zirconia, nitride ya silicon. Isoko ryuzuye risabwa, gusesengura ibyiza byubwoko butandukanye bwibikoresho.
Carbide ya silicon ifite ibyiza byigiciro gito ugereranije, kurwanya isuri nziza, imbaraga nyinshi, ibibi bikomeye biroroshye okiside, biragoye gucumura. Alumina niyo ihendutse cyane, kandi gahunda yo gutegura ibikoresho byifu yifu irakuze cyane, mugihe zirconi na silicon nitrous oxyde ifite imbogamizi zigaragara muriki cyerekezo, nacyo kikaba kimwe mubibuza kubuza iterambere ryibiri ryanyuma. Silicon nitride, byumwihariko, niyo ihenze cyane.
Kubijyanye nimikorere, nubwo imbaraga, ubukana nibindi bikoresho bya mehaniki ya nitride ya silicon na zirconi biruta kure alumina, birasa nkaho imikorere yikiguzi ikwiye, ariko mubyukuri hariho ibibazo byinshi. Ubwa mbere kuva zirconi, ifite ubukana buhanitse, impamvu ni ukubaho kwa stabilisateur, ariko ubukana bwayo bukabije butita ku gihe, ntibushobora gukoreshwa ku bushyuhe bwo hejuru kandi ubushyuhe bw’icyumba bukabuza cyane iterambere ridakuka rya okiside, hakwiye kuvugwa ko ari gito muri bitatu ku isoko. Nitride ya silicon, nayo ni ceramic izwi cyane mumyaka makumyabiri ishize, imbaraga zidashobora kwangirika zumuriro nubundi buryo bwuzuye nibyiza, ariko gukoresha ubushyuhe buri munsi yizindi ebyiri; Gahunda yo gutegura nitride ya silicon nayo iragoye kuruta alumina, nubwo ikoreshwa rya nitride ya silicon iruta cyane zirconiya, ariko kugereranya muri rusange ntabwo ari byiza nka alumina.
Imikorere ihendutse, ihamye, ibicuruzwa bitandukanye bya alumina ceramics byabaye imikoreshereze yambere, kandi byakoreshejwe mububumbyi bwihariye.
