The standard molar enthalpies of formation, Df H/C14 m (298.15 K), of Pb2CrO5(s) and Pb5CrO8(s) were determined using an isoperibol calorimeter. The enthalpies of solution of pure compounds, namely, Pb2CrO5(s) and Pb5CrO8(s), as well as mixtures such as {PbCrO4(s) + PbO(s)} and {PbCrO4(s) + 4PbO(s)} in HNO3 (aq., 8 mol/dm³) at T = 298.15 K were measured. Using these values, the standard molar enthalpies of formation, Df H/C14 m (298.15 K), of Pb2CrO5(s) and Pb5CrO8(s) were determined as (1171.5 ± 1.7) kJ/mol and (1850.6 ± 8.7) kJ/mol, respectively. This study contributes significantly to the understanding of the thermochemistry of lead chromates, which is imperative for applications in lead-cooled nuclear reactors and other advanced systems. Such data are crucial for predicting the stability and reactivity of these compounds under operational conditions.
