Methods used to analyze the regularities of the course of thermally activated processes are considered. It is shown that the most informative and reliable are non-isothermal methods. On the example of alumina materials modified with eutectic additives of the systems MnO - Al 2 O 3 - SiO 2 , CaO - ZnO - Al 2 < / sub> O 3 - SiO 2 and ZnO - TiO 2 , it was found that the densification kinetics obeys the first-order formal kinetics equation. The apparent activation energies of sintering have been determined. Calculation of the laws of sintering by methods of non-isothermal kinetics allows you to design the modes of heat treatment of products. Il. 1, bibliography: 4 titles.
