Effect of dopants on the sintering behaviour and stability of tetragonal zirconia ceramics [PDF]
, 1992 The microstrueture development during non-isothermal and isothermal sintering has been studied for tetragonal zireonia ceramics (TZP) containing carious amounts of Y, Ce and Ti. Smaller grain sizes were obtained when Ce-TZP was doped with yttrium.
