摘要：
Surface tensions of Ni3S2, Cu2S and FeS molten phases were measured using an improved sessile drop method in an inert atmosphere of purified argon. The traditional sessile drop method was modified before measurements were obtained. The surface tension values were obtained over a wide range of temperature from their respective melting temperatures to 1300 degrees C. In the temperature range 1000-1300 degrees C, surface tension of molten Ni3S2 decreased linearly with increasing temperature. However, the surface tensions of molten FeS and Cu2S phases were approximately constant over this range of temperature.
