The grain size distributions (GSDs) in 3 mol% yttria-stabilized zirconia (3 Y-TZP) which had been isothermally annealed for various times at 1300 °C and 1400 °C without and with a weak DC electric field 
=18 V/cm were determined. The GSDs for all test conditions fit a single curve whose form is in accord with the Bitti–Di Nunzio model, and moreover is in accord with the GSDs for sintering and plastic deformation. The results for all three processes suggest the GSD to be a unique function of the mean linear intercept grain size.
