What is it about?

We develop a phase-field model with diffusion-controlled processes at interfaces for isothermal dissolution of alumina inclusion particles in molten silicates, referred as ‘slag’, with comprehensive compositions applied in process metallurgy. The interfacial energy between solid inclusion particle and molten silicate can vary with different temperatures and chemical compositions. This model is validated using experimental data of high temperature laser confocal scanning microscopy (HT-CLSM) technique.

Why is it important?

It is the first time to predict the real size inclusion dissolution time by the phase field methods.


Hope this work can pave the way on how to utilize the phase field method to investigate the oxide particle in slag referring to the steelmaking.
