抄録

In tetravalent network materials like quartz or ice the main interactions are the strong bonds that connect each vertex to four others and the repulsive forces that keep non-bonded vertices further apart. Those interactions, modelled by square wells, are shown to be sufficient to account for the stability of ice-like crystals, with tetrahedral bond angles, at low temperature; endothermic melting of the crystal to a denser water-like amorph at intermediate temperatures; exothermic collapse of the supercooled crystals at high pressure, to a glass, without breaking any bonds; expansion on cooling of both the crystal and the amorph; and a line of spinodal instabilities in the water-like supercooled amorph where the compressibility, heat capacity and negative expansivity diverge.
