The importance of alpha -clustering effects in the interior region of heavy nuclei is estimated by studying the existence of such phenomena in infinite nuclear matter assuming a crystalline type of structure where each lattice site is occupied by an alpha -particle. The crystalline alpha -matter is described in terms of the microscopic alpha -particle model of Margenau, Bloch and Brink and its saturation propenties are compared with those of the plane wave model for two different nucleon-- nucleon interactions, namely the Brink densities of nuclear matter the plane wave model turns out to be more stable than the alpha - cluster, indicating that the alpha -type correlations are not important in the interior region of heavy nuclei, however at a density of approximately one--third of the central nuclear density a transition from the independent particle model to the correlated alpha -cluster crystalline model occurs, suggesting the importance of such correlation on the nuclear surface.
