Initial wetting phenomena and spreading property of CaO-SiO2 slag on MgO single and poly-crystal refractory substrates are investigated using sessile drop technique and a high-speed camera (1 500 frame's). By observing and analyzing the spreading rate, change of the contact angle, and the composition change in slag and refractory, we found that the initial wetting is non-reactive and controlled by viscous friction.
