Measurements of thermal expansion of ESR slags for the systems CaF 2 + Al 2 O 3 + CaO and CaF 2 + MgO. Hysteresis in thermal expansion data for some slags indicates the formation of microcracks in the slag during cooling. A simple model for the estimation of thermal contraction values for ESR slags is proposed.
