| Abstract | Cobalt-doped forsterite ceramic pigments based on the formula (Mg2-2xCo2x)SiO4 (x = 0, 0.05, 0.1, 0.2) were synthesized using mirror wastes as a flux. Addition of this flux enhanced forsterite phase formation at lower temperature by as much as 200?. The resulting pigment particles were in a micron range which is suitable for use in a ceramic glaze. The host structure (Mg2SiO4) could accommodate cobalt cations up to 20 at%. Investigation on the chemical distribution revealed that no chemical species from the flux reacted with pigment grains. Optical properties were examined by UV-vis spectroscopy and colorimetry. Technical performance of the obtained pigments was tested in an industrial low-fire glaze. Alteration in color of the matured glazes was clearly observed, suggesting some instability of the pigments. Using a dense pellet form embedded in a molten glaze, an interfacial layer was observed, indicating interaction between the pigment and corrosive glassy glaze occurred. Stability in all raw materials commonly used in medium-fire glazes was further studied in order to determine which compound might cause such instability. The results would allow a design of glaze's recipe to possess the desired color of the finished products. |
