SURFACE TENSION OF BLAST FURNACE TYPE SLAGS CONTAINING TITANIUM OXIDES
含氧化钛高炉型渣表面张力的测定

The surface tension of quinary blast furnace type synthetic slags containg titanium oxides has been measured by means of sessile drop method. The influences of TiO_2, MgO and basicity on the surface tension of the slag has also been studied. It was found that TiO_2 is a surface active component. The surface tension of quinary slag may increase as TiO_2 was substi- tuted by the same quantity of lower-valent titanium oxides.
