In this study, Sb x Sn 1−x O 2 (0 ≤ x ≤ 0.5) compositions were synthesized by the ceramic method from Sb 2 O 3 ‐SnO 2 and Sb 2 O 5 ‐SnO 2 mixtures and characterized by Differential thermal analysis (DTA) and thermogravimetric analysis (TG), X‐ray diffraction, UV‐V‐NIR spectroscopy and CIE L*a*b* (Commission Internationale de l'Eclairage L*a*b*) parameters measurements. Solid solutions with cassiterite structure were obtained at 1300 °C. These solid solutions are stable into glazes. From Sb 2 O 3 , light gray coloured materials were obtained. From Sb 2 O 5 , bluish gray coloured materials were obtained at 1300 °C/6h when x ≥ 0.3. Sb x Sn 1−x O 2 with 0.3 ≤ x < 0.5, T = 1300 °C and Sb 2 O 5 might be established as compositional range, fired temperature and antimony precursor to obtain gray ceramic pigments in this system.
