Ka 'marakeng, re tloaelane le lisebelisoa tse khethehileng tsa ceramic: silicon carbide, alumina, zirconia, silicon nitride.Tlhokahalo e felletseng ea mmaraka, sekaseka melemo ea mefuta ena e mengata ea thepa.
Silicon carbide e na le melemo ea theko e tlase haholo, ho hanyetsa khoholeho e ntle, matla a phahameng, bothata bo boholo bo bonolo ho oxidize, ho thata ho sintering.Alumina ke eona e theko e tlaase ka ho fetisisa, 'me mokhoa oa ho lokisetsa lihlahisoa tsa phofo o hōlile haholo, ha zirconia le silicon nitrous oxide li na le mefokolo e totobetseng tabeng ena, e leng e' ngoe ea litšitiso tse thibelang tsoelo-pele ea tse peli tse qetellang.Silicon nitride, haholo-holo, ke eona e theko e boima ka ho fetisisa.
Mabapi le ts'ebetso, le hoja matla, boima le lisebelisoa tse ling tsa mechine ea silicon nitride le zirconia li molemo haholo ho feta alumina, ho bonahala eka ts'ebetso ea litšenyehelo e nepahetse, empa ha e le hantle ho na le mathata a mangata.Pele ho tloha zirconia, e na le toughness e phahameng, lebaka ke ho ba teng ha stabilizer, empa toughness ea eona e phahameng ke nako e nahanelang, e ke ke ea sebelisoa ka mocheso o phahameng le mocheso oa kamore ea nako-sensitive ka botebo thibela tsoelo-pele e fosahetseng ea oxidation, e lokela ho ba. a re ke e nyenyane ho tse tharo tse marakeng.'Me silicon nitride, e boetse e le ceramic e tummeng lilemong tse mashome a mabeli tse fetileng, matla a ts'oarellang a mocheso le ts'ebetso e' ngoe e pharaletseng e ntle, empa tšebeliso ea mocheso e tlase ho feta tse ling tse peli;Mokhoa oa ho itokisa oa silicon nitride o boetse o rarahane ho feta alumina, le hoja ts'ebetso ea silicon nitride phase e molemo haholo ho feta zirconia, empa papiso ka kakaretso e ntse e sa tšoane le alumina.
Ts'ebetso e theko e tlaase, e tsitsitseng, mefuta-futa ea lihlahisoa tsa lirafshoa tsa alumina e bile tšebeliso ea pele, 'me e sebelisitsoe ho lirafshoa tse khethehileng tsa hona joale.
