FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing a cobalt pigment and can be used to produce paint materials, different types of ceramics and for art and restoration work. The method of producing blue aluminium-cobalt pigment involves preparation of starting reaction aqueous solutions containing a cobalt (II) salt and an aluminium (III) salt, precipitation of a precursor product from the solution, separation from the solution, washing with water, drying and firing. The precipitant used is a strongly basic anionite gel AV-17-8 in hydroxide form, and firing is carried out at temperature of 750°C.
EFFECT: ion-exchange method of producing spinel-based pigments without using aggressive media, high temperatures and pressure.
