摘要：

We describe three-dimensional froths obtained by radical tessellation of random binary assemblies of spheres at different packing fractions C from C=0 to C similar to 0.60 and for large ranges of composition. The packings are built numerically using different algorithms: collective reorganization, random deposition or molecular dynamics interaction. Both topological and metric properties show deviations from those of a totally random froth. The results are qualitatively similar to those obtained previously on 2D binary mixtures of disks.
