Abstract
High-temperature oxide melt solution calorimetry with molten 2PbO.B2O3 as a solvent can be used for determining enthalpies of formation of carbonates and hydrous silicates. Under conditions of gas flow at 1-2 cm3/s, all H2O and CO2 is expelled from the solvent, leading to a reproducible final thermodynamic state. Both analytical data and a number of thermodynamics cycles show that, under these conditions, the volatiles neither dissolve in nor interact energetically with the melt. -Authors
