Dihedral angle solid-state sintering

Figure C2.11.7. An illustration of tlie equilibrium dihedral angle, 0, fonned by tlie balance of interfacial energies at a pore-grain boundary intersection during solid-state sintering.

In solid-state sintered ceramic systems, densification and microstructure development can be assessed on the basis of the dihedral angle, 0, formed as a result of the surface energy balance at the pore-grain boundary intersection.
