摘要：

General equations to correlate and predict the thermodynamic properties of hydrated berates were developed based on the experimental results according to their structural types. The thermodynamic properties (Delta H-f(0) and Delta G(f)(0)) of a hydrated borate phase are the sum of the contributions of the cations in aqueous solution, the borate polyanions, and the structural water to the corresponding thermodynamic properties. This method is called the group contribution method, and it is extensively used to calculate the thermodynamic properties of many kinds of inorganic compounds, such as silicates and clay minerals.
