Vatsvagiri vekuJapan vakashandisa polycrystalline diamond maturusi kucheka Al2O3 ceramics uye Si3N4 ceramics. Zvakaonekwa kuti coarse-grained polycrystalline diamond maturusi aive asina kupfeka zvishoma panguva yekucheka uye maitiro ekugadzirisa aive akanaka. Pakucheka ZrO2 ceramics nematurusi edhaimondi, yakasvika Mhedzisiro yacho yakafanana neyekucheka simbi. Vakaongorora miganhu yekeramic plastiki yekucheka. Iyo yakakosha yekucheka kudzika kweAl2O3 ceramics ndeye apmax=2um, SiC ceramics apmax=1um, Si3N4 ceramics apmax=4um (ap>apmax, ceramic zvinhu zvinoburitsa kutadza kusimba; kana ap
