Fluid-solid phase-separation in hard-sphere mixtures is unrelated to bond-percolation

Abstract
In a recent letter, Buhot proposes that entropy driven phase-separation in hard-core binary mixtures is directly related to a bond-percolation transition. However, at least for binary hard-sphere mixtures, calculations based on an accurate approximation to g_{ll}(r) demonstrate that n_b varies widely along the phase-boundaries calculated directly by simulations, implying that bond-percolation is unrelated to the phase-separation in these systems.
