Abstract:

This paper presents the synthesis method of V-ZrSiO4 solid solutions (ZrVxSi1-xO4 and ZrVxSiO4, x = 0.05, 0.10, 0.15) based on products of plasma dissociated zircon which treated by ammonium hydrofluoride NH4HF2 aiming to explore the potential of this technology in the manufacturing of ceramic pigments. Green pigments were obtained by calcination of mixtures of fluorinated plasma dissociated zircon with vandium pentoxide at 1000 – 1500 °C. Blue pigments were obtained using mineralizer sodium fluoride NaF at 750 °C. The use of fluorinated plasma dissociated zircon led to higher yield of green and blue color of pigments. The increase of the calcination temperature of blue pigments made lower blue color yield due to formation of orange colored V-ZrO2 solid solutions
