Applications of Calorimetry in the Field of Thermodynamic Properties of the Aqueous Borate Systems

摘要

Owing to the high performance of borate crystals, they are widely used in the fields of mobile communications and other high technology. Researches on thermodynamic properties of aqueous borate systems are essential for the synthesis of borates and the comprehensive utilization of boron-containing brine resources. The calorimeter technique is a new experimental precision method for thermodynamic property measurement. The characteristics of calorimeter technique, standard molar formation enthalpies of alkalis borates and alkalis earth borates, and the thermodynamic properties of aqueous borate systems were summarized in this paper. The key problems in the study of the thermodynamic property of borates and the new trend in the future were also pointed out.
