英文摘要
In order to unravel the structure of H2O- and CO2- bearing silicate melts, we have synthesized silicate glasses of a range of compositions using piston cylinder apparatus and internally heated gas pressure vessel, and have characterized them by various NMR techniques as well as Raman spectroscopy. Quantum chemical calculations were also performed to assist data interpretation. This study has provided new insights into the compositional dependency of H2O and CO2 dissolution mechanisms in silicate melts. It was confirmed that CO2 is dissolved in depolymerized silicate melts dominantly as free carbonates, i.e. carbonate species not linked to the silicate network, and dominantly as network carbonates and molecular CO2 in fully polymerized silicate melts.
