Part of the mission of the Bureau of Mines is to provide values of thermodynamic properties for minerals and related inorganic compounds. As part of this effort, the molar heat capacity of sodium zirconium oxide was measured from 5 to 305 k by adiabatic calorimetry and from 438 to 1,168 k by differential scanning calorimetry. The molar enthalpy of formation was determined by hydrofluoric-acid solution calorimetry. The molar enthalpy of formation at 298.15 K is -(1,686.3 +/-2.0) Kj.Mol-1. The values at 298.15 K of cp,m, sm(t)-sm(0) , and - gm(t)-hm(0) /t are 125.88, 125.50, and 54.88 J.K-1mol-1, respectively. These functions are also calculated from 5 to 1,170 k.
