| Abstract: | Further considerations concerning thermal decomposition of reference material — CaCO3, described by three-parametric equation in version (3), have been presented. It was established that in linear relationship
between coefficients of Eq. (3) a
2 is the argument of a
1, which reaches minimal value of thermodynamic character (δH/vR) when a
2=0 (equilibrium relationship). During thermal decomposition connection between system atmosphere — rich in CO2 or vacuum, caused by fast evacuation of gaseous products — and activation energy value, as well as maximal temperature of
reaction process. Conditions of this kind may be explained by Zawadzki-Bretsznajder law. |
