Deoxidation of high-melting-point metals and alloys in …

Through melting, refractory metals and alloys are becoming important for use as structural materials. Vacuum-melting is considered to be able to provide high-purity ingots because of its purifying effect, particularly the effect of evaporation deoxidation via volatile oxides. Thermodynamic calculation leads us to predict a limited possibility for deoxidizing Ti, Zr, Hf, a good possibility for

Physical Properties - Chemistry

For a given compound, this temperature represents its melting point (or freezing point), and is a reproducible constant as long as the external pressure does not change. The length of the horizontal portion depends on the size of the sample, since a quantity of heat proportional to the heat of fusion must be added (or removed) before the phase change is complete.
