Change in the melting temperature of metals with an increase in pressure

A new analytical (i.e., without computer modeling) method for calculating the dependence of melting temperature T m a single-component crystal on pressure P is proposed. The based delocalization criterion and does not contain fitting constants. baric dependences (P) its derivative T' gold, platinum niobium in range: P=0-1000 GPa were calculated by this method. It was shown that gold agree better with experimental data than obtained simulation methods. For niobium, turned out to be steeper, i.e., value larger experiment. indicated discrepancy might due both decrease Lindemann parameter increasing redistribution electrons s-d-orbitals during compression transition metals BCC structure. Keywords: point, pressure, interatomic interaction, platinum, niobium.
