The author proposes that metals may be melted by induction in a supported metal crucible in order to reach high purity levels. The crystallization conditions for the column of liquid metal are represented by a mathematical model which of such parameters of the metal as its relative emissivity, crystallization temperature, specific conductivity, electromagnetic field penetration depth, column radius, and magnetic field strength at the surface. Another series of equations is used to calculate the optimum height of the column relative to the deposition of electromagnetic energy and the melting and crystallization rates. A table presents calculated maximum heights at which crystallization occurs for the following metals: aluminium, vanadium, tungsten, heat resisting steel, cobalt, molybdenum, nickel, niobium, platinum, titanium and chromium.
