| Abstract: | The acid-base equilibria in the liquid silicates in the system PbO–SiO2 are discussed, Data reported by Richardson and Webb, wherein the PbO activity is determined over a composition range of 0 to 60 mole % SiO2, are used for comparison with activities computed from structural models with consideration of the acid-base equilibria. The results suggest that the liquid silicates in the system PbO–SiO2, for the composition and temperature ranges studied, are constituted of a relatively low number of anionic species and that these anions are of a relatively small size (i.e., O2–, SiO4–, (SiO3)36?. and (SiO2.5)66?). |
