Develop spinel structure and quantify phase transformation for nickel stabilization in electroplating sludge

Develop spinel structure and quantify phase transformation for nickel stabilization in electroplating sludge

Ni in the electroplating sludge can be incorporated into NiFe2O4 and NiAl2O4 spinel structures, when two typical ceramic precursors (α-Fe2O3 and γ-Al2O3) were used respectively. The transformation ratio of Ni into the either spinel can reach over 99%. The two spinels exhibit superiority in Ni stabil...
