The core objectives of understandin

The core objectives of understanding sintering kinetics is to predict densification behavior under different processing conditions and to obtain a uniform microstructure at high density with controlled grain size. In solid state sintering, the constant heating rate of anisothermal sintering is known to influence on densification and grain growth behavior, where faster heating rate leads to higher densification and finer microstructure at same temperature due to increases volumetric strain rate. Furthermore, nonlinear sintering temperature has processing advantages for finely regulating the path of morphological change. Hence, the proposed study is intended to identify anisothermal densification kinetics of ZnO cold sintering and to quantify relevant activation energy. Advancing the sintering kinetics knowledge is a necessary condition to develop a complete analytical model, which will certainly accelerate cold sintering composite materials research and application deployment.
