Abstract

This paper presents thermodynamic modeling results for the magnesium reduction of the MgTa2O6, Mg4Ta2O9, and LiTaO3 tantalates. We have calculated the temperature-dependent heat capacity of the tantalates and determined the adiabatic temperature as a function of initial reactant temperature for reduction reactions in the MgTa2O6-5Mg, Mg4Ta2O9-5Mg, 2LiTaO3-5Mg, and 2LiTaO3-6Mg systems and the equilibrium phase composition of these systems.
