Model Studies of Microstructure Changes in Sintering of Ceramics

Abstract:

In this article an experiment is described which is included into a course in materials science and allows for better understanding of a nature of sintering. It is a fusion of a computer simulation and a physical experiment – both performed in model systems. Part I of the experiment concerns microstructure of powders. Packing density and coordination numbers of the grains in the sintered powder are analysed with application of computer simulation. In part II of the exercise, the kinetics of the sintering of glass grains is measured via microstructure-evolution observations. The results may be used to discuss the mass transport mechanism.
