Abstract

Results of a study of ceramic compaction kinetics under conditions of isothermal and nonisothermal heating are given. Kinetic equations of the compaction process using a structure/energy parameter as the dependent variable are given, and on this basis values of apparent activation energy for two compaction stages are determined. It is demonstrated that modification transitions and formation of unstable phases and solid solutions in the course of ceramic firing have a substantial effect on the mechanism of ceramic compaction.
