Abstract

It is shown that quite generally there is a correlation between insulator-metal transition pressures and indentation hardness numbers for covalent crystals. They are numerically equal for the Group IV elements. Three elements plus five III–V compounds acquire the β-Sn structure upon metallizing. Bondbending, rather than bond-shortening, appears to lead to their transformations. A simple version of the theory of covalent bonds gives the critical transformation bond-angle correctly.
