The Effect of Ni Ions Substitution on Structural, Morphological, and Optical Properties in CoCrO Matrix as Pigments in Ceramic Glazes.

The structural, morphological, and optical properties of Ni ions substitution in CoCrO matrix as ceramic pigments were investigated. The thermal decomposition of the dried gel was performed aiming to understand the mass changes during annealing. The X-ray diffraction (XRD) studies reveal a spinel-type Face-Centered Cubic structure and a secondary CrO phase when x ≤ 0.
