讨论了PbO - SiO₂体系中液态硅酸盐的酸碱平衡。使用了Richardson和Webb所报道的数据（其中在SiO₂含量为0到60摩尔%的组成范围内测定了PbO的活度），以便与考虑酸碱平衡的结构模型所计算出的活度进行比较。结果表明，对于所研究的组成和温度范围，PbO - SiO₂体系中的液态硅酸盐由相对较少数量的阴离子种类构成，并且这些阴离子的尺寸相对较小（即O²⁻、SiO₄⁻、(SiO₃)₃⁶⁻和(SiO₂.₅)₆⁶⁻）。
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−).
