用座滴法测定了1600°C时硒、碲对铁水表面张力和铁水对氧化铝润湿性的影响，并与氧、硫的影响进行了讨论。(1)硒和碲作为表面活性剂，其表面活性按氧、硫、硒和碲的顺序增加。(2)铁液与氧化铝之间的接触角随氧的加入而减小，随硒和碲的加入而增大。而硫对接触角几乎没有影响。(3)随着这些元素含量的增加，铁液与氧化铝之间的界面自由能减小。(4)铁液与氧化铝的粘附功随硫、硒、碲含量的增加而减小，随氧含量的增加而增大。
Effects of selenium and tellurium on the surface tension of molten iron and on the Wettability of alumina by molten iron were measured with sessile drop method at 1600°C and results were discussed together with those of oxygen and sulphur.The main results are as follows.(1) Selenium and tellurium acted as the surface active agents and the surface activity increased in the order of: oxygen, sulphur, selenium, and tellurium.(2) The contact angle between molten iron and alumina decreased with the addition of oxygen and increased with the additions of selenium and tellurium. While, sulphur scarcely affected the contact angle.(3) The interfacial free energy between molten iron and alumina decreased with the increasing of these elements.(4) The work of adhesion between molten iron and alumina decreased with the increasing of sulphur, selenium, and tellurium, and increased with the increasing of oxygen.
