High-pressure phenomena - Compression, Superconductivity, Diamonds

High-pressure phenomena - Compression, Superconductivity, Diamonds: High-pressure X-ray crystallographic studies of atomic structure reveal three principal compression mechanisms in solids: bond compression, bond-angle bending, and intermolecular compression; they are illustrated in Figure 1. Bond compression—i.e., the shortening of interatomic distances—occurs to some extent in all compounds at high pressure. The magnitude of this effect has been shown both theoretically and empirically to be related to bond strength. Strong covalent carbon-carbon bonds in diamond experience the lowest percentage of compression: roughly 0.07 percent per GPa. Similarly, ionic bonds between highly charged cations and anions, such as bonds between Si4+ and O2− in silicates, are relatively incompressible (less
