Abstract    The microwave-assisted polyol method was implemented to prepare vanadium-containing nanopigments of ZrSiO4. The influence of microwave power (300-900 W) and irradiation time on the purity, crystallinity, and particle size of the synthesized nanoparticles was studied. The X-ray diffraction, Fourier transform infrared (FTIR), electron microscopy (FESEM/TEM) and dynamic light scattering (DLS) analyses were performed to characterize the features of nanopigments. XRD analysis shows that the 300 W synthesized powder is composed of solid amorphous particles. Increase microwave power to 900W to convert all particles to crystalline nano-ZrSiO4. The experiment revealed the critical influence of irradiation time and microwave power on purity and crystallinity. The microwave effect can accelerate the reaction and the nucleation rate of ZrSiO4 at a lower reaction temperature. The nanoparticles obtained were tested as ceramic pigments, and the colorimetric parameters of CIELab were measured. Structure and colorimetric studies have confirmed that a fully crystalline zircon phase can be obtained at 1100 °C and can be used as a blue pigment.
