“In the field of green ceramic pigments, researchers have successfully synthesized novel Y3Ga3MgSiO12: xCr3+ (x = 0-0.2) pigments using the conventional solid-state approach. The study reveals that the trivalent chromium ions occupy the [Ga1O6] octahedral sites within the garnet lattice, and the relatively weak crystal field environment provided by the matrix endowed the pigments with green characteristics. The samples prepared by calcination at 1400 °C exhibit the most excellent performance in terms of phase purity, morphology, and color properties. The chromaticity values for the representative sample Y3Ga3MgSiO12: 0.05Cr3+ are L* = 81.16, a* = -12.53, and b* = 12.71, and the color remains stable after the stability test. Moreover, when glazed with Y3Ga3MgSiO12: xCr3+ (x = 0-0.2) pigments, the smooth glaze surfaces exhibit vivid and saturated green tones, demonstrating their remarkable coloring capabilities and promising potential as a practical pigment for medium-temperature applications. This research underscores the vast application prospects of Y3Ga3MgSiO12: Cr3+ as an innovative green ceramic pigment.”
