Synthesis of ZnO-Al2O3-Cr2O3 Pigments and Coloring in Glazes

다국어 초록 (Multilingual Abstract)

ZnAl1-x CrxO4 solid solutions were synthesized as pink pigments with and without mineralizer. The pigments were examined to
optimize color development conditions of temperature and Cr2O3 contents. The characteristics of synthesized pigments were analyzed
by XRD, XPS, FT-IR and UV-vis spectrophotometer. While samples without mineralizer fired at 1300oC, showed ZnAl2O4 and
ZnCr2O4 spinel in XRD analysis. While samples with mineralizer resulted in ZnAl2O4. As a results, the pigments show pink color
and most effective pink color was obtained at X=0.15 and 1250oC when mineralizer was used. The chromatic coordinates are L* 58.61 a* 24.48, and b* 9.60.
