Synthesis and characterization of red pigment YAl1−yCryO3 prepared by the low temperature combustion method

In the present study, a red-shade pigment, based on the system YAl1−yCryO3 (y = 0–0.05), was synthesized for the first time using the low temperature combustion method. The single-phase synthesis of YAl1−yCryO3 was achieved at a temperature of 1000 °C. The resulting calcined powders were micron-sized particles (0.5–3 μm) with a well-developed cubic perovskite structure. The study specifically investigated the chemical composition, calcination temperature, Cr3+ content, and the effect of the mineralizer in order to elucidate the optimal conditions for pigment synthesis. Further, the color properties exhibited by the YAl1−yCryO3 pigment when it was added into basic glazes have also been obtained. In addition, the products were characterized by DTA, XRD, FESEM, EDX, and color spectrometry.
