  Volume shrinkage, grain growth, and their interaction are major events
occurring during free sintering of ceramics. A high temperature sintering
dilatometry curve is influenced by these both phenomena. It is shown that the
continuum theory of sintering can be utilized in the format enabling the
extraction of the maximum amount of information on the densification and grain
growth kinetics based on a simple dilatometry test. We present here the
capability of such a fast approach (Dilatometry based Grain growth Assessment
DGA) utilized for the modeling of sintering and grain growth of zirconia.
