Synthesis of Forsterite Pigment for Underglaze Colors
The aim of the present investigations was to synthesize pigments based on Ni-doped forsterite (Mg2SiO4) for high temperature underglaze colors by ceramic route. In forsterite Mg2+ can be replaced by Fe2+, Ni2+, Co2+ ion since their ionic radious are close or coincide. NiO doped forsterite green pigments pigments were prepared by ceramic method from mixture of MgO and SiO2 and H3BO3 as mineralizer and the colour properties of the pigments was also investigated. In this experiment, very brilliant and fluorescent light green color hue of pigment was obtained at 1300°C for 3 hours. According to various firing condition, crystalline structure of pigments were chracterised by X-ray diffraction and FT-IR, Raman spectroscopy. And their color characterization were analized by UV-Vis spectroscopy on the ground of CIE L*a*b* measurement.
