Sintering kinetics of high-alumina ceramics with complex additive

The results of studies of the kinetics of ceramics compaction during sintering under isothermal and non-isothermal heating conditions are presented. Kinetic equations of the compaction process are given using the structural-energy parameter as a dependent variable, on the basis of which the values ??of the apparent activation energy for two stages of the compaction process are determined. It is shown that modification transitions, the formation of unstable phases and solid solutions in the process of ceramics firing have a significant effect on the mechanism of its compaction.
