چکیده انگلیسی
Yellow inorganic pigments PrxZr1-xSiO4 (xâ¯=â¯0-0.08) have been prepared by a novel non-hydrolytic sol-gel (NHSG) method at 750â¯Â°C for 2â¯h. Replacing Pr4+ for Zr4+ in ZrSiO4 increased the cell volume and changed the color from white to yellow gradually. The SiâOâZr and SiâOâPr bands were observed in the FT-IR spectra of xerogel, indicating it could reach homogeneous mixing at the atomic level. Therefore, it promoted the solid solution reaction between Pr and zircon at low temperature. The samples exhibit high doping limitation (xâ¯=â¯0.08) and brilliant yellow hue (b*â¯=â¯69.48) in contrast with the previously reported praseodymium zircon yellow pigments. The intense of yellow hue was increased with increasing the Pr doping content due to the increase of Pr4+/Pr3+ species. After applying on bisque ceramic tiles, the pigment exhibited excellent coloration, high thermal stability and low solubility in molten glazes, indicating its potential application in ceramic decoration.
