Abstract

The methods used to analyze the regularities of thermally activated processes are discribed. It is shown that the most informative and reliable methods are the isothermal methods. The data on the initial components and their conversion ways to experimental samples in the technological scheme are presented. In the example of alumina materials modified with various amounts of various eutectic additives it was found that the sintering process obeys the equation of the first order kinetics formal. The apparent activation energy of sintering and initial patterns for the development of optimum firing mode of the materials are determined.
