A novel population balance model based on size interval-by-size interval ma
rching algorithm has been developed for the transient grain growth kinetics
during solid state sintering. This model incorporates the coupled phenomen
a of densification and grain growth and exhibits reasonable capability of p
redicting the temporal evolution of grain size distribution for a given ini
tial grain size distribution and time-temperature sintering cycle. In this,
part II of our work, we present the coupled governing equation for sinteri
ng kinetics. We employ a size interval-by-size interval marching algorithm
for the solution of the resulting population balance equation and validatio
n of the model against experimental data for zirconia compacts sintered at
1400, 1500 and 1600 degreesC for different times. In addition, the model ha
s been successfully tested against published experimental data on sintering
of alumina compacts. (C) 2001 Elsevier Science Ltd and Techna S.r.l. All r
