Pfeka inodzivirira ceramic iyo inonyanya kuumbwa inosvika 90% Al2O3 ndiyo inonyanya kushandiswa munyika nhasi.
Zvigadzirwa zvedu zvinogadzirwa kubva kune yakanyatsosarudzwa alumina poda ine yunifomu particle sizes uye yakaderera CaO content.Wear inodzivirira ceramics inogona kugadzirwa kuburikidza neyakajairwa yakaoma mushini kana isostatic yekutsikirira maitiro uye wobva wainyudza pakupisa kwakanyanya muchoto.Iwo anodiwa emidziyo yekupfeka yemidziyo yekupfeka yakakwira nekuda kwehukuru chaihwo, kusimba kwepamusoro, yakakwirira alumina yemukati, yakanaka flatness uye yakagadzikana mhando.
