Master sintering curve with dissimilar grain growth trajectories: A case study on MgAl2O4

Sintering is a key step in the processing of high performance ceramics. Both density and grain size play crucial role on ceramic sintering kinetics final material properties. The master curve (MSC) well-known tool for exploring models kinetics. However, conventional MSC theory assumes unique trajectory, while our study MgAl2O4 spinel shows dissimilar growth response. Park's has been applied compared with approach obtaining activation energy without trajectories.
