- This work utilized a quantitative phase-field model (PFM) to investigate dissolution behaviours of different oxide particles in various slag systems. The simulations could evaluate the influences of temperature, slag viscosity and slag composition on the dissolution time/rate of oxide particle. The simulated results are consistent with reported experimental data. A critical temperature and slag viscosity ratio (T/v), at which the MgAl2O4 and Al2O3 particles have the same dissolution rate, was determined as similar to 1190 [K/Pa's]. It is impossible to get a fixed dissolution time/rate order of different oxide particles in general slag compositions due to the complicated variations of interfacial mobility coefficients. The Al2O3 particle is more sensitive to the variation of MgO and Al2O3 components in slag, compared with the MgAl2O3 particle. When the V-ratio (CaO/SiO2) increases up to a certain degree, the influence of MgO component in both MgAl2O3 and Al2O3 particles becomes minor.
