Description
The standard molar Gibbs free energy of formation of Na2ZrO3(s) has been obtained by measuring equilibrium pressures of CO2 for the reaction: Na2CO3(s) + ZrO2(s) Na2ZrO3(s) + CO2(g) by a static manometric method in the temperature range 878 to 1107 K. Δsub(f)Gsub(m)0Na2ZrO3(s) has been evaluated and can be represented by Δsub(f)Gsub(m)0(Na2ZrO3, s, T)/(kJ · mol-1) = -1676 + 0.348(T/K) ± 1.1. Second-and third-law analyses yielded Δsub(f)Hsub(m)0(Na2ZrO3, s, 298.15 K) as -(1662.9 ± 7.6) and -(1654.9 ± 8.02) kJ · mol-1, respectively. (author)
