Low Temperature Melting of Elements under High Pressure and Its Progression in the Periodic Table

Data Obtained and gathered to data regarding melting phenomena in elements and compounds have been both reviewed and summarized in this paper. The result has yielded information concerning a new melting relation for materials, the characteristics of which are described in the following three items. 1) Any solid possesses a maximum melting point at a characteristic applied hydrostatic pressure. 2) At any temperature below the maximum melting point the solid melts at two characteristic pressures. 3) The pressure corresponding to the maximum melting point is lower in a solid composed of elements having a larger mass number; the progression of pressure for the maximum melting point is evident in each group elements in the periodic table.
