The diffusivity of lead in a PbO‐SiO2 melt was determined as a function of oxygen pressure from kinetic data for the oxidation of liquid lead covered by a layer of lead silicate melt which is short‐circuited to facilitate electronic transport. The diffusivity‐oxygen pressure relation thus obtained agreed well with the corresponding prediction based on definitions of the fluxes ofPb2+ and electron holes and an appropriate equilibrium relation.
