Phase equilibria in (water + krypton) at pressures from 31 MPa to 273 MPa and temperatures from 610 K to 660 K and in (water + neon) from 45 MPa to 255 MPa and from 660 K to 700 K

The blast furnace process (BF) continues to be the principal technique used for ironmaking in the world. The oxide system CaO-SiO2-Al2O3-MgO forms the major components of final slags tapped from BF. Recommended phase diagram sections with different contents of Al2O3 and MgO have been summarised in Slag Atlas [1], which are mainly based on the works reported by Osborn et al. [2] and Cavalier and Sandrea-Deudon. [3] However, it has been demonstrated in recent reviews and measurements of selected slags that significant differences are observed for the phase diagrams in the Al2O3-CaO-MgO-SiO2 system between these recent studies [4-6] and those presented in the early research.
