The present work was carried out with a view to re‐examine the phase diagram aspects of CaOAl 2 O 3 SiO 2 and CaOMgOAl 2 O 3 SiO 2 slags with MnO additions. The aim was to confirm the homogeneous liquid range necessitated for sulfide capacities measurements of the above‐mentioned slags. The liquidus and solidus temperatures of these slags were measured by DSC and X‐ray radiograph techniques. The experimental results were compared with the liquidus and solidus temperatures obtained from literature (Slag Atlas) and commercial softwares ThermoCalc and FactSage. The results indicate that there is good agreement between the experimental values and those retrieved from literature and the commercial software in the case of the ternary system CaOAl 2 O 3 SiO 2 . For the CaOMgOMnOAl 2 O 3 SiO 2 system, significant deviations were observed between the different sources. The present observations indicate that X‐ray radiography can be a very useful tool in estimating the solidus temperatures of slags while DSC would complement the information with respect to liquidus temperatures.
