Meta-study on the effect of P2O5 on single phase slag viscosity and the effect of P2O5 induced liquid phase immiscibility on dispersion viscosity

Investigations on the viscosity behavior of gasification slags with special respect to P2O5 are scarce. Therefore, a meta study was performed compiling relevant knowledge its effect melt compositions similar slags. The data showed whether oxide behaves acidic and as network former how changes varying basicity single-phase melt. A supplementary since previous paper anomaly bearing slag that is included in study. In order investigate phenomenon, quench analyses were investigated via XRD SEM-EDX. found be caused by miscibility gap at certain temperature. quite common two resulting phases clear difference composition but could well predicted FactSage 7.2. model modified so it worked case undercooling. An average relative error only 18 20 % for main oxides temperature points without
