Tessellation of binary assemblies of spheres

We describe three-dimensional froths obtained by radical tessellation of random binary assemblies of spheres at different packing fractions from to 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
