Abstract
The article presents a thermodynamic calculation of the modifi ation of hypereutectic silumin by cerium, beryllium and antimony. It has been shown that in the melt of hypereutectic silumin, cerium, beryllium and antimony refine elementary silicon nanocrystals from adsorbed oxygen atoms. The process of modifying primary silicon microcrystals with cerium, beryllium and antimony has been studied. These metals increase the concentration of elementary silicon nanocrystals free of oxygen atoms in the melt of hypereutectic silumin. This process increases the concentration of crystallization centers and increases the dispersion of primary silicon microcrystals.
