Paragraph starter

The selection of materials for high-temperature processing equipment, such as crucibles in pyrometallurgical recycling, can significantly influence the efficiency of resource recovery. For instance, research by Holzer et al. (2021) demonstrated that using an MgO crucible resulted in up to 97% lithium recovery from LCO cathode materials, a substantial improvement over the 76% achieved with an Al2O3 crucible, highlighting the critical role of material-process interaction in optimizing recycling yields.
