The objective of this presentation is to contribute to the understanding of the role that grain boundaries play in sintering. It is a phenomenological overview of how they behave and why. Specific functions to be covered are the formation of grain boundaries, their nature and movement. This discussion is based on the foundation of our knowledge on the sintering of ceramics established by an excellent tutorial review by Coble and Burke in 1963.1 Their chapter lists many references on specific aspects of sintering.
