Abstract

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.

(Cr,V)-ZrSiO4宝石绿颜料的合成及其近红外反射性能

采用900℃原位矿化法制备了新型(Cr,V)-ZrSiO4宝石绿颜料。通过DTA-TG、XRD、FE-SEM、TEM、UV-Vis-NIR、比色仪等手段研究了Cr/Si摩尔比的影响。结果表明，随着Cr/Si摩尔比从0增加到0.4，颜料的颜色呈现出由蓝色到宝石绿色，再到深绿色的变化趋势。当Cr/Si摩尔比为0.2时，(Cr,V)-ZrSiO4颜料呈现宝石绿色(L* = 56.69, a* = 18.52, b* = 9.28)，呈现良好的显色性能。此外，所制得的颜料在1200℃合成的基础釉中表现出良好的热稳定性。C和近红外反射性能。本研究结果显示了该颜料在隔热方面的巨大潜力。
