Vaongorori vekuJapan vakashandisa maturusi edhaimani epolycrystalline kucheka Al2O3 ceramics neSi3N4 ceramics. Zvakaonekwa kuti maturusi edhaimani epolycrystalline ane grained grained akanga asina kunyanya kusakara panguva yekucheka uye mhedzisiro yekugadzirisa yaive yakanaka. Pakucheka ZrO2 ceramics nemidziyo yedhaimani, yakasvika. Mhedzisiro yacho yakafanana nepakucheka simbi. Vakaongorora miganhu yekucheka purasitiki yeceramic. Kudzika kwakakosha kwekucheka kweAl2O3 ceramics ndekwe apmax=2um, SiC ceramics apmax=1um, Si3N4 ceramics apmax=4um (ap>apmax, zvinhu zveceramic zvinokonzeresa kutadza kushanda zvakanaka; kana ap
