Abstract

Using rice husk ash as silica, the influence of the firing temperature and keeping time on the color intensity of the Pr-ZrSiO4 Pigments were investigeted.The Pr-yellow pigments were calcined at 500, 700, 800, 900, 950, 1000, 1100 by ceramic method. The synthesized pigments were chracterised by DT-TG thermal analysis, X-ray diffraction, UV-Vis spectroscopy, SEM-EDAX analysis. The relationship of Zircon phase formation-growth and Pr-yellow color development were evaluated and optimum firing conditions has been determined.
