| Popis: | Novel (Cr,V)-ZrSiO4 jewel green pigments were synthesized by in situ mineralization at 900°C. The effects of Cr/Si molar ratio were investigated via DTA-TG, XRD, FE-SEM, TEM, UV-Vis-NIR, colorimeter and etc. The obtained results referred that the colour of pigment exhibits blue to jewel green, and then to dark green as the Cr/Si molar ratio increases from 0 to 0.4. When the Cr/Si molar ratio is 0.2, the (Cr,V)-ZrSiO4 pigment exhibits a jewel green hue (L* = 56.69, a* = −18.52, b* = −9.28), showing good rendering performance. In addition, the obtained pigment shows good thermal stability in the base glaze synthesized at 1200°C and near-infrared reflection performance. The results of this study show great potential for using the pigments for heat insulation. |
