Abstract

Both vapor transport and surface diffusion can lead to neck growth during sintering without densification and are thus undesirable. However, vapor transport and its effects on the densification kinetics and microstructure development of ceramics has been probably the most neglected transport phenomenon both experimentally and theoretically. Nevertheless, it is an ideal process with which to study microstructural development in powder compacts since the transport coefficients are easily controlled, are readily available in the literature or easily calculated. This is in contrast to the lack of control over solid, surface, and boundary diffusion coefficients for which there is additionally a paucity of data.
