Themelting pointof a substance is the temperature at which it changes state from solid to liquid at atmospheric pressure; at the melting point, the solid and liquid phases exist in equilibrium. A substance's melting point depends on pressure and is usually specified at standard pressure in refer...
A six-colour pyrometer has been used to measure the melting point and the emissivity of nine refractory metals: hafnium, niobium, molybdenum, rhenium, rhodium, tantalum, tungsten, vanadium, and zirconium. In several metals and conductive ceramics the isotherms of the emissivity ελ are found to...
PURPOSE:To measure a melting point accurately, by obtaining a temperature curve for temperature of material to be measured solidified by cooling with a monochromatic radiation thermometer to determine temperature of a dichroic radiation thermometer when a thermal arrest occurs on the temperature curve. ...

For some materials at the melting point the heat capacity is modeled as Dirac delta function [57]: (32)Cp(T)=cp(T)+ΔEδ(T−Tmelt),cp(T)={cp,1(T),T<Tmeltcp,2(T),T>Tmelt.ΔE is the enthalpy jump and cp, 1, cp, 2 are usually continuous. This is the case for copper...
