Thermal analysis was used to study the behavior of various cobalt oxides (CoO, Co 2 O 3 and Co 3 O 4 ) when heated. At 200 - 850 & # 176; C Co 2 O 3 gradually passed into Co 3 O 4 , which at & # 8776; 920 & # 176; С turned into CoO. The effect of mechanical treatment in a planetary and ball-ring mill on the yield of CoAl 2 O 4 spinel and the size of its crystallites at different temperatures is analyzed. The effect of MgO and ZnO additives on the size of pigment particles and color is estimated. The synthesized compounds were tested as pigments introduced into engobe, glaze, underglaze and overglaze paint using several ceramic masses
