Abstract
Methods used for analyzing the regularities of thermally activated processes are considered. It is demonstrated that the most informative and reliable are nonisothermal methods. Taking the example of alumina materials modified by eutectic additives of systems MnO-Al2O3-SiO2,CaO-ZnO-Al2O3-SiO2, and ZnO-TiO2, it is established that their consolidation kinetics obeys a first-order formal kinetic equation. The apparent energy of sintering activation is determined The calculation of sintering regularities by nonisothermal kinetic method makes it possible to design schedules for heat treatment of articles.
