Abstract
We review recent lattice QCD results for the surface tension at the fi nite temperature quark-hadron phase transition and discuss their impli cations on the possible scale of inhomogeneities. In the quenched appr oximation the average distance between nucleating centers is smaller t han the diffusion length of a proton, so that inhomogeneities are wash ed out by the time nucleosynthesis sets in. At present lattice results are inconclusive when dynamical fermions are included.
