| Abstract: | Summary On the basis of calorimetric research of selenium dioxide, zirconium dioxide and zirconium diselenite dissolution reactions in the hydrofluoric acid solution under 298 K a standard enthalpy of Zr(SeO3)2 formation reaction from ZrO2 and SeO2 and a standard enthalpy of zirconium diselenite formation have been obtained. The value of enthalpy has been equal to -58.1±3.43 kJ mol-1 in ZrO2(solid)+2SeO2(solid)  Zr(SeO3)2(solid) reaction. The standard enthalpy of zirconium diselenite formation is equal to  Hf,2980Zr(SeO3)2(solid)= -1603.2±3.8 kJ mol-1. The Hf,2980 Zr(SeO3)2(solid) value has been determined for the first time. |
