An orthogonal test method was employed to improve compositions of the raw material glaze.Subsequently,Pr-Ce-ZrSiO4 yellow ceramic pigment was incorporated into the solid phase method to synthesise a yellow glaze for building ceramics,optimised for low-temperature fast firing.Additionally,the effects of calcination temperature and Pr/Ce molar ratio on the color presentation of color glazes were investigated.The experimental results demonstrate that when the ratio of the base glaze is colemanite∶lithium feldspar∶quartz∶fluorite,the following outcomes are produced.BaCO3∶The Sr-CO3 ratio of 15∶52∶20∶4∶5∶8 allows for the production of a high-quality glaze with excellent gloss.The calcination temperature of 1 200℃is optimal for the Pr-Ce-ZrSiO4 yellow color pigment,as it allows for maximal penetration of Pr4+ions into ZrSiO4 crystals,resulting in superior glaze coloring.The glaze exhibits an optimal coloring effect when the Pr/Ce molar ratio is 1∶0.55.At this ratio,Ce4+and Pr4+can replace Zr4+to form a limited solid melt,reducing the green hue of the color glaze.This results in a transition from yellow to orange-yellow in the glaze color.
