Analysis of Secondary Refining Slag Parameters with Focus on Inclusion Cleanliness [PDF]
Materials Research, 2018 Secondary refining slag samples with different chemical compositions (45-54 % CaO, 7-13 % Al2O3, 20-29 % SiO2, 9-16 % MgO, 0-5 % CaF2) were investigated to verify the influence of their effective viscosity on inclusion cleanliness of DIN 38MnS6 in a steelmaking plant.

The Canadian Journal of Chemical Engineering, EarlyView.Abstract This study proposes a novel, green, and sustainable method for synthesizing magnetic iron oxides from metallurgical copper slag (CS), leveraging its iron content as a valuable resource. Iron was extracted via acid leaching using edible citric acid (ECA), forming a citrate–iron complex (CSL), which was subsequently thermally decomposed at 300°C

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT This paper examines whether occupational pension funds (OPFs) apply a strategic and long‐term logic when assessing ESG practices in their investee firms. Using discourse analysis of semi‐structured interviews with asset managers and workers' representatives, we examine whether Spanish OPFs look beyond compliance‐driven CSR and consider the ...

Corporate Social Responsibility and Environmental Management, EarlyView.ABSTRACT Research on supermarket‐related voluntary sustainability standards (VSSs) is divided on whether competition helps or hinders efforts to reduce negative social and environmental impacts. This paper examines how the standardization process shapes these outcomes.

Crystallization of Cathode Active Material Precursors from Tartaric Acid Solution
ChemSusChem, Volume 18, Issue 6, March 15, 2025.This work investigates a novel approach for closing the gap between recycling and production of lithium‐ion battery cathode material. The new concept is based on antisolvent crystallization of metal carboxylates, which can be directly used as precursors in production of cathode material.

Removal of SiC and Si3N4 inclusions in solar cell Si scraps through slag refining
High Temperature Materials and Processes, 2022 Silicon was recovered from solar cell Si scraps through 42.5 mol% SiO2–42.5 mol% CaO–15 mol% Al2O3 slag refining. The motion behaviors of Si3N4 and SiC were observed in situ and real-time using a high-temperature laser confocal microscope, and the ...
