There is an increasing research interest of yellow pigment for coloring ceramics that must show thermal and chemical stability at high temperature [1]. Throughout history various yellow ceramic pigments have been used: yellow of vanadium-zirconia, tin-vanadium yellow, cadmium yellows, lead antimoniate , etc. The praseodymium zircon (Pr-ZrSiO4) yellow ceramic pigment is believed to be a solid solution of Pr4+ with the zircon lattice, but studies are poor and scarce [2]. The aim of this work, is the synthesis of Pr-ZrSiO4 yellow pigment in the presence of NaF and NaCl by the method of mixing metal oxides and to investigate the nature of the pigment. The Pr-ZrSiO4 particles are characterized by XRD, SEM and XRF to analyze their structure and morphology. The results show that particles of Pr-ZrSiO4 was synthesized, has particle size about 60-1000 nm by olivine-baddeleyite structure.
