Impact of atmospheric water vapor on the kinetics of the induction period of the thermal dehydration of lithium sulfate monohydrate

Abstract

The thermal dehydration of lithium sulfate monohydrate (LSM) exbibits significant induction period (IP) prior to mass-loss process under isothermal conditions. The average rate of IP is well described by conventional Arrhenius-type temperature dependence. The kinetic behavior of IP dramatically changes by the influence of the atmospheric water vapor pressure, p(H2O). In this study, a universal kinetic description for the induction period under various temperature, T,and p(H2O) was trialed through formalizing an accommodation function, a(p(H2O),P eq(T)),on the basis of classical nucleation theory. Characteristic kinetic behavior of the IP process is discussed by reviewing the results of the universal kinetic approach.
