Thermal analysis was used to study the behavior of different cobalt oxides (CoO, Co2O3, and Co3O4) upon heating. At 200 – 850°C Co2O3 gradually transforms into Co3O4, which at about 920°C transforms into CoO. The effect of mechanical working in planetary and ball-ring mills on the yield of the spinel CoAl2O4 and its crystallite sizes at different temperatures was analyzed. The effect of the dopants MgO and ZnO on the pigment particle sizes and color was evaluated. Using several ceramic bodies, the synthesized compounds were tested as pigments introduced into engobe, glaze, and under- and overglaze paint.
