The dissolution of stoichiometric particles within a melt plays a crucial role in various material processes. This study presents a comprehensive phase-field model to analyze the dissolution behavior of these stoichiometric particles under experimental conditions. Our approach addresses the classical phase-field challenges related to modeling stoic...
The viscosities of Na2O-TiO2-SiO2-CaO-MgO-Al2O3 slags were measured to enhance understanding of the effect of Na2O and TiO2 on the viscous behavior. An increase in the Na2O content lowered the viscosity but adding TiO2 increased the viscosity. The transformation of the structural units was investigated using in-situ temperature -dependent Raman spe...

During pyrometallurgical extraction, some metals are lost to the slag phase which limits the process efficiency and may also cause environmental harm if those slags are used afterwards for the concrete industry. One way to reduce metal losses is via slag cleaning in a submerged arc electric furnace (SAF) where heat is generated via the conversion o...
Different nascent structures during polyethylene growth can impact the final polymer properties. So far, the evolution of the aggregation structure of nascent polyethylene is still unknown. We have developed a nascent polyethylene model and investigated the effect of confined space on the nucleation and crystallization process. The in situ polymeri...

The goal of this work is to assess the applicability of the concept of a "slag foaming index" on industrial data. For this purpose, process data from the steel plant of ArcelorMittal Ghent are used. An acoustic measurement is used to identify the heats with high levels of slag foaming. A model based on process data is developed to estimate the slag...
