Random close packing of spheres in a round cell

Spectroscopy studies of structural phase transitions of chalcogenide glass thin films (Ge2S3)x(As2S3)1−x at coordination number 2.67

“…After structural transformation to 3D network occurs, when average coordination number exceeds 2.68, structure resembles more closely the structure of an ideal amorphous solid. Long et al [28] showed that the highest percentage of fixed spheres has six contacts with surrounding spheres while most of the 'rattler' spheres have four or five contacts. After the structural transformation spheres become more closely packed so it can be assumed that the number of contacts per sphere was increased which resulted in more fixed spheres in the structure.…”

The cluster model: A hierarchically-ordered assemblage of random-packing spheres for modelling microstructure of porous materials

“…However, models constructed by this procedure are intended to describe not the growth process of real systems, but the final state of such systems. They are categorised as static models [31].…”

Fluctuations, structure factor and polytetrahedra in random packings of sticky hard spheres

“…The second family, that of static-or sequential-methods, is based on the progressive insertion of spheres in the aggregate, tangentially to three already inserted spheres. In this case, the sphere is immediately assigned its definitive position and various strategies exist to build random systems in this way ( [8,9]). Such approaches have been proven able to describe the structure of pure or binary liquids and amorphous metals and alloys [10] and are of interest to describe penetration [11], segregation effect [12], growth of tumor [13]...…”
