The isothermal grain growth of PLZT ceramics with various La concentrations from 0 to 10 at. % is studied. For all La concentrations, the sintering time (t) dependence of grain size (D) is expressed in the normal grain growth formula, D n = Kt. The constants n and K greatly depend on the La contents. These facts indicate that there are several grain growth mechanisms related to the La concentrations in PLZT ceramics.
