Thermodynamic Study of High-Purity TiSi2 Prepared by Directional Solidification
The equilibrium segregation coefficient of impurities in materials is the theoretical basis for its purification. This study used the high-temperature chemical equilibration technique to determine the solid solubility and the approximate equilibrium segregation coefficients of Fe, Mn, Al, Cu, and Ni impurities in TiSi2. The results showed that the solid solubilities of Al, Fe, Mn, Ni, and Cu in TiSi2 were in the range of 1.0 to 1.5 wt pct, and their equilibrium segregation coefficients were less than 1.
