非平衡凝固法制备金属间化合物SbSn的表面结构

锡-锑系统的研究由于其重要的的理论意义和应用价值而受到重视，但是各个相图之间并不是完全一致的。大部分对于金属间化合物SbSn的研究集中在平衡态，对于金属间化合物SbSn的结构研究尚存在着一些不同的看法，对于锡锑的相图和金属间化合物SbSn的晶体结构还需要进一步的研究。

Surface Structure of Intermetallic Compound SbSn Prepared by Non-equilibrium Solidification

Intermetallic compound SbSn of different crystal structure was prepared by melting rapidly quench. Surface structure of obtained material was characterized by AES and XPS. Results revealed that the contents of Sb in the surface of material (a) prepared at the condition of voltage 30 V, current 400 A, and quench speed 30 m·s^-1 were greater than that (b) prepared at the condition of voltage 20 V, current 20 A, and quench speed 30 m·s^-1, and the valence state of Sb in the surface of the material prepared at the first condition was +3; while that prepared at the second condition was zero. The structures and desulfurization performance of material prepared at different quench speeds were studied. Result shows that the material being prepared at the condition of voltage 30 V, current 400 A, the composition of trigonal system crystal structure increase with the quench speed, and its desulfurization performance was also enhanced with the quench speed.
