Cesium zirconium silicate compounds

Shibanov et al. [78SHI/CHU] measured the standard enthalpy of formation of Cs2ZrSi207(s) in a 10% HCl solution using an isothermal platinum calorimeter. The enthalpy of the solution was found to be - (218.8 1.3) kJ-moP. From this value, the authors calculated the standard enthalpy of formation to be  

This value is selected with the uncertainty estimated by this review. The enthalpy is similar in magnitude to the isostructural sodium compound (see Section V.7.2.5).
