Classifying stages of the anisother

Classifying stages of the anisothermal sintering. Considering the slope change of the ZnO cold sintering shrinkage curves, at least three different dominant processes can be hypothesized, which include 1) solution–assisted particle rearrangement, 2) powder densification by pressure solution creep and 3) grain growth and pore removal (Fig. S8). Such a claim can be considered as logical, as rearrangement will initially occur with the presence of uniaxial pressure and liquid phase in the system, but eventually stops due to the loss of the liquid and the formation of coarse grains, making less likely to continue the particle sliding.
