Apr 24, 2019 · However, it was found that the pigment colour deterioration with the decrease in particle size. To explain it, yellow Pr-ZrSiO 4 and blue V-ZrSiO 4 pigments with particle sizes of 0.5 μm–2.2 μm were used in this work. The results show that the decrease of particle size will result in the low chromatic values of the pigments and glaze
