The heat of dissolution of these products in a phosphoric acid solution was measured by a C-80 SETARAM microcalorimeter. A thermochemical cycle was proposed and complementary processes were carried out in order to get the standard enthalpies of formation of these apatites. Estimation of the values...
For that a thermochemical cycle was investigated and the obtained value for the standard molar enthalpy of formation of rubidium diphosphate is (3,183.7) kJmol 1 . The result is about 1.8% lower than literature value.doi:10.1007/s10973-014-4023-9Gmati-Ben Khaled, H....

As nano ZnO and bulk ZnO possess the same reaction essence, the relationship between standard molar enthalpies of formation of nano ZnO and bulk ZnO was built by designing a novel thermochemical cycle. Combined with microcalorimetry, standard molar enthalpy of formation of the as-prepared ZnO ...
[41] investigated two thermochemical cycles by solution calorimetry and the enthalpies of formation from elements of Li4P2O7 were -3147 and -3383.4 kJ·mol-1, respectively. The difference could be attributed to the presence of solid LiCl in cycle 1. Show abstract Experimental and thermodynamic ...
