Abstract: Experimental results obtained from the in situ observation of the dissolution of spherical Al2O3 particles in CaO-Al2O3-SiO2-containing melts at elevated temperatures are analyzed using a lattice Boltzmann dissolution model. Through a comparison of the experimental dissolution curve with analytical predictions and numerical simulations, the rate-limiting step is identified as diffusion control. Estimations of the effective binary diffusion coefficient are obtained, together with an estimate of the activation energy for the diffusion process. (c) 2008 American Institute of Physics.
