Abstract
ln pCO2(Pa) (±0.13)=−15722.8T+26.83 (755≤T(K)≤987) forln pCO2(Pa) (±0.13)=−18615.7T+29.90 (773≤T(K)≤989) forEu2O2CO3 decomposition.
From the above vapor pressure expressions, the median enthalpy and entropy of the decomposition of the oxycarbonates were calculated by the second law analysis and their thermodynamic stabilities were derived. The results are discussed in the light of available thermochemical data of the compounds.
