The calcination kinetics of ammonium pentaborate was investigated by thermo
gravimetry (TG) using the Coats-Redfern and genetic algorithm methods. Vari
ous methods for determining the reaction parameters using thermal analysis
data were improved. Genetic algorithms can be considered as a new method fo
r the determination of kinetic parameters by TG. In this study, the genetic
algorithm procedure is applied to the determination of the coefficients of
reaction (activation energy, frequency factor, and order of reaction) and
their relative standard deviations, The Coats-Redfern method was applied to
the same TG; data to calculate the reaction parameters. The results obtain
ed from both methods were also compared.
