Structural Evaluation of Silicate Melts by Performing Impedance Measurements and Quasichemical Model Calculations

    Research output: Contribution to journalArticlepeer-review

    Abstract

    Structures of molten oxides (including silicates) strongly affect their physical properties. Although structural analysis is typically performed experimentally by nuclear magnetic resonance and Raman spectroscopy or theoretically by employing thermodynamic quasichemical and cell models, these techniques are time-consuming, and their results are not sufficiently accurate. In this study, high-precision structural evaluations were performed within a relatively short timeframe by combining impedance measurements with the quasichemical model. For this purpose, correlation equations, including the thermodynamic parameters of the quasichemical model and equivalent circuit components obtained by impedance measurements, were derived. Using the proposed method, the evaluation accuracy was improved by approximately 3.6 times as compared with the data generated by FactSage software.
