- •
The glass-ceramic samples were proven to be excellent in immobilizing Cr.
- •
Glass-ceramic was successfully synthesized in CaO-MgO-SiO2-Al2O3 -Cr2O3 system.
- •
Both crystalline and glass phases were quantified by Rietveld quantitative XRD.
- •
The partitioning ratio of Cr into spinel in the glass-ceramic can be up to 90%.
