Ceramic materials sintering characteristics

The analysis of integral and local compaction during sintering of ceramic materials is carried out. A model is proposed that describes the structure of the material during sintering and takes into account the process of clustering of particles constituting the material. Formulas for micro- and macroporous space (coordination number, specific surface area and average pore size) and an algorithm for their calculation are obtained. The calculation according to the model showed that at the beginning of sintering the size of macropores sharply increases.
