Pamusika, isu tinonyanya kujairana neakakosha ceramic zvinhu: silicon carbide, alumina, zirconia, silicon nitride. Yakazara kudiwa kwemusika, ongorora mukana weaya akati wandei marudzi ezvishandiso.
Silicon carbide ine mabhenefiti emutengo wakachipa, kunaka kwekukukurwa kwevhu, kusimba kwepamusoro, kukanganisa kukuru kuri nyore kuita oxidize, zvakaoma kunyura. Alumina ndiyo yakachipa, uye magadzirirwo ehupfu mbishi zvinhu zvakakura kwazvo, nepo zirconia nesilicon nitrous oxide zvine zvakaipira zviri pachena mune izvi, zvinova zvakare chimwe chezvipingamupinyi zvinotadzisa kuvandudzwa kwemaviri ekupedzisira. Silicon nitride, kunyanya, ndiyo inodhura zvakanyanya.
Panyaya yekushanda, kunyange zvazvo simba, kuoma uye mamwe maitiro e-silicon nitride uye zirconia ari nani kupfuura alumina, zvinoratidzika kuti mutengo wekuita wakakodzera, asi chaizvoizvo kune matambudziko akawanda. Kutanga kubva ku zirconia, ine kuoma kwepamusoro, chikonzero chiripo chekudzikamisa, asi kusimba kwayo kwakanyanya kunoenderana nenguva, haigone kushandiswa pakupisa kwepamusoro uye tembiricha yekamuri nguva-inonzwa zvakakomba kurambidza kuvandudzwa kusiri kweiyo oxidation, zvinofanirwa kutaurwa kuti ndiyo idiki pane matatu ari pamusika. Uye silicon nitride, zvakare yakakurumbira ceramic mumakore makumi maviri apfuura, kupfeka-kusagadzikana kwekushisa kwesimba uye mamwe maitiro akazara akanaka, asi kushandiswa kwekushisa kwakaderera pane mamwe maviri; Nzira yekugadzirira yesilicon nitride yakanyanya kuoma kupfuura alumina, kunyange zvazvo kushandiswa kwesilicon nitride chikamu chiri nani kupfuura zirconia, asi kuenzanisa kwese kuchiri kusina kunaka sealuminium.
Kusingadhure, kuita kwakagadzikana, kusiyanisa kwechigadzirwa kwealumina ceramics kwakava kushandiswa kwekutanga, uye kwakashandiswa kune yazvino yakakosha ceramics.
