“…Due to the similarity of the ionic radii of Ce 3+ and Ca 2+ , Ce 3+ can enter the augite phase by replacing Ca 2+ 34 . The bond energy of Ce–O is much higher than that of Ca–O, 35 which is conducive to improving the mechanical properties of glass‐ceramics. In summary, the heavy metal replaces the light metal into the crystal, which effectively cures the heavy metal while reducing the toxicity of the glass‐ceramic and achieving perfect curing of the heavy metal.…”

“…The comprehensive utilization of BFS includes its use in the production of cement, slag bricks, silicon fertilizer, and glass ceramics. The main constituents of BFS are CaO (35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48) wt.%), SiO 2 (28-42 wt.%), MgO (3-14 wt.%), and a small amount of Fe 2 O 3 (0-2 wt.%). 5 Glass-ceramic is a polycrystalline solid material consisting of microcrystalline and glass phases.…”

Glass‐ceramics with high performance and high crystallinity was produced using rare earth blast furnace slag (REBFS) as the primary raw material, along with composite nucleating agents Fe2O3 and Cr2O3. The migration pattern, distribution characteristics, and solidification properties of heavy metals in glass‐ceramics were investigated by the controlled heat treatment. The findings indicated that the heat treatment temperature has a significant effect on the distribution and color of heavy metals in glass‐ceramic. In the crystallized glass‐ceramic, spinel acts as the crystal core for heavy metal solidification, Cr, Cu, and Mn can exist stably in the spinel by the solid solution. The glass‐ceramic was expected to be used as a decorative building material.
