The kinetics of solid‐state reactions toward consensus, Part 3. Searching for consistent kinetic results: SCTA vs. conventional thermal analysis

Abstract

AbstractThis paper is the third part of a review of some of the controversial kinetic aspects of conventional thermal methods. We open a discussion about the necessity of developing new possibilities and techniques in the field of solid‐state reactions. In the last decade we have seen the commercialization of new instruments and apparatus by a number of manufacturers, which allows for carrying out more meaningful experiments. The Sample Controlled Thermal Analysis describes a family of new techniques such as Controlled Rate Thermal Analysis, Stepwise Isothermal Analysis, etc., which are based on the use of their own rate of reaction for controlling the reaction temperature. It is shown that these new approaches have much more effective control on heat and mass transfer phenomena and can provide enhanced resolution and sensitivity and improved kinetic data. © 2002 Wiley Periodicals, Inc.
