The phenomena of penetration of liquid slag into solid bulk lime and into the cracks of the lime body have been investigated by in‐situ X‐ray direct observation. The lime samples were immersed into CaO‐SiO 2 ‐Fe t O‐MgO molten slag at 1350, 1450 and 1550°C. It was found from the results that the height of slag penetration into the lime bulk linearly proportional to the penetration time. The rate of penetration at high temperature is much greater than that at low temperature whereas the slag penetration into a crack in the lime body slows down gradually and the penetration reaches an equilibrium height in the course of the experiments. Higher T.Fe content and temperature are favourable to lime dissolution into molten slag and thus to the penetration into both lime body and cracks. Molten slag with high FeO can completely wet solid lime.
