Incorporation of Galvanic Waste (Cr, Ni, Cu, Zn, Pb) in a Soda-Lime-Borosilicate Glass

In the present investigation, a glassing process for galvanic waste (GW) incorporation with a high chemical stability is presented. Glasses with up to 50 wt% of galvanic solid waste by modifications in the basic composition of soda–lime–borosilicate glasses were prepared. After fusing at temperatures up to 1300°C, the glasses were characterized by inductively coupled plasma, scanning electron microscopy/energy‐dispersive X‐ray spectroscopy, high‐temperature microscopy, transmission and reflected light microscopy, nuclear magnetic resonance, X‐ray photoelectron spectroscopy, and X‐ray diffraction methods. The chemical stability was evaluated by hydrolytic attack assays. Glasses containing up to 40 wt% of GW with a very high chemical stability, similar to bottle glasses, were obtained.
