Abstract RU 2054443 C1

FIELD: the invention relates to processes for preparing colored inorganic pigments for use in the paint industry and in the manufacture of microplastic materials. SUBSTANCE: the process comprises preparing mixture composed of compounds from pigment-forming components and urea in amount sufficient to assure at least zero oxygen balance of the original reaction mixture, dehydrating the mixture and calcining at 450-500 C. EFFECT: simplified and lower energy consuming process, broader color range of pigments, eg blue cobalt aluminate and yellow calcium chromate. 2 tbl
