Résumé : |
The polyol method was implemented to prepare stable V–ZrSiO4 suspensions as ceramic ink. It was shown how the rheology, surface tension, viscosity, and particle size of suspensions were affected by the length of polyol solvent and dispersants. The effect of ethylene glycols, diethylene glycol (DEG), triethylene glycol, and tetraethylene glycol as solvents, as well as polyvinylpyrrolidone (PVP) and cetyltrimethylammonium bromide as dispersants on the ink properties was investigated. The X-ray diffraction, Fourier-transform infrared (FTIR), electron microscopy (FESEM/TEM) and dynamic light scattering analyses were performed to characterize the features of nanopigments. Crystalline V–ZrSiO4 nanopigment was obtained at 1100°C by DEG solvent in the presence of PVP. The sizes of the resulting nanoparticles were in the range of 10–50 nm. The achieved suspensions were tested as ceramic inks on a tile, and the colorimetric CIELAB parameters were measured. The CIE L*a*b* values confirmed the blue color. The surface tension and viscosity of prepared ceramic ink, as well as microstructure of the annealed nanopigments, were in the range required for drop-on-demand inkjet printers. |
