Application of a diffusion model to oxide sintering
Abstract
The application of a diffusion model to sintering rate data developed for lithium titanium ferrite was investigated. The data were obtained by sintering pressed pellets under identical conditions for various times up to 11 hours. Stereological measurements were made on polished sections, and sintering rates were calculated. A model for intermediate stage sintering was fitted to the stereological data. This procedure produces a method by which these type data are used to study the relative importance of volume and grain boundary diffusion under a variety of sintering conditions.
