| Abstract | Abstract The wetting behavior of molten CaO-Al2O3-SiO2 slags on a Al2O3 substrate was investigated using the sessile drop method at 1873K. For the slag compositions along the CaO saturation range, the wetting angle increased with increasing SiO2 content up to 20 wt.% of SiO2, but further increase in SiO2 resulted in decrease in the wetting angle. For a same CaO/SiO2 ratio, the wetting angle increased with increasing Al2O3 content. Using the experimental results maps were constructed for iso-wetting angles and iso-spreading rates. The MgO addition greatly increased the wetting angle and showed a maximum value at MgO content of about 3.5 wt%. |
