| Abstract |
The dependence of the elastic properties of monatomic (simple substances) and diatomic (AB type compounds) crystals of the cubic syngony on the types of their crystal structure and interatomic bond is analyzed. It is shown that the elastic properties of these crystals follow one of two trends, covalent or ionic. The auxetics (materials with a negative Poisson's ratio) are identified among monatomic crystals with the A1 structure (fcc), such as to alkaline earth, transition and post-transition metals, actinides, and lanthanides, as well as among monatomic crystals with the A2 structure (bcc), such as to alkali metals. Among binary diatomic compounds, the largest number of auxetics is found among diamond-like crystals with the B3 structure (zinc blende) and stoichiometry ANB8−N. |
