Synthesis and Study of the Physical and Optical Properties of the Composite Pigments of Cr2O3-SiO2 and Cr2O3-TiO2 by Using Ceramic Method
Abstract:   (1294 Views)
In this research Cr2O3-SiO2 and Cr2O3-TiO2 green pigments have been fabricated using a mixture of Cr2O3-SiO2 and Cr2O3-TiO2 powder by ceramic method. The samples have been homogenized using planetary mill in a solvent with a ratio of 1:4 for 5 h and then printed on the ceramic using screen printing method and heated in the industrial condition. The crystal structure of samples, the shape and the size of the particles and their optical properties have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis spectroscopy and CIE L*a*b* colorimetric methods. The XRD results show two-phase structure has been created in both samples. The average of crystallite size for Cr2O3-SiO2 and Cr2O3-TiO2 were measured 40 and 34 nanometers, respectively. The SEM images show that the average size of Cr2O3-SiO2 and Cr2O3-TiO2 are 290 and 143 nanometers, respectively. The physical properties of printed ceramic were investigated by SEM and colorimetric methods. The average particle size for printed samples, Cr2O3-SiO2 and Cr2O3-TiO2, on the ceramic were measured 131 and 106 nm respectively.
