N2 - Ionic transport in the molten system PbO-SiO2 is discussed based upon available data on lead and silicon tracer diffusivities, interdiffusion coefficients, electrical conductivity and on measured values of lead and silicon transference numbers. The interrelationship of these parameters is illustrated through a theoretical treatment of the phenomenological transport equations. The Onsager transport coefficients for the independent set of equations are calculated for melt compositions between 0.3 < xSiO2 < 0.6 at 850 °C The coincidence of large changes in the transport parameters between the orthosilicate and metasilicate compositions and the large changes in the silicate structure is discussed.
