Title
Kinetics of Solid-State Reactions: a Thermal Analysis Approach
Luis A. Pérez-Maqueda, Pedro E. Sánchez-Jiménez and José M. Criado
Summary
Solid-state
reactions,
including
solid-solid
reactions,
gas-solid
reactions,
decompositions, etc, are of paramount importance in nowadays technology. Thus, they
are involved in processes such as preparation of ceramic materials, corrosion, resin
curing, CO2 Ca-looping, thermal degradation of materials, etc. A very important aspect
of those processes is the kinetics of the involved reactions. Knowledge of the kinetics of
those processes is of great interest for different reasons. Thus, first of all, it allows
modeling the behavior of the system under heating conditions different from those used
in the lab for performing the experiments. Moreover, kinetic parameters provide an
insight into the processes that takes place during the transformations. Those processes
are usually quite hard to study with conventional experimental techniques and any
additional information, as that provided from the kinetic analysis, allows a better
understanding of the involved reactions.
Thermal analysis techniques are very useful for obtaining experimental data required for
the determining the kinetic parameters, as far as they provide information of the
macroscopic evolution of the samples as a function of the temperature and time. Thus,
conventional thermal analysis techniques such as thermogravimetry, differential thermal
analysis, differential scanning calorymetry, dilatometry, etc are commonly used in those
studies. Hyphenated techniques are nowadays becoming more popular as they provide
complementary information. Obtaining kinetic parameters from a set of experimental

data requires of mathematical methods such as isoconversional analysis or model fitting
procedures. In the case of complex processes deconvolution or non-linear regression
procedures have been proposed.
In this presentation, both experimental procedures and mathematical methods used in
our lab for determining the kinetic parameters are presented, while a number of
examples are presented.
