Summary

Sintering (here pressureless sintering) means compactation and subsequent heat treatment of ceramic or metal powders. Sintering usually goes along with neck growth between neighboring powder particles and shrinkage, i. e. vanishing of pore space. In this article we will discuss the influence of changes in the microstructure on the sintering process.
