Keywords:
borates, Gibbs energy, inorganic acids, dissolution, mineralsAbstract
The thermodynamic characteristics ΔH0f,298 ΔG0f,298 ΔS0f,298 for 11 borate minerals. From the calculated energy ΔGbdata to dissolve the boron minerals of various inorganic acids ustanvoleno that the best solvent is sulfuric acid.References
