METHOD FOR PRODUCTION OF PIGMENTS HAVING METALLIC SHINE Russian patent published in 1995 - IPC

Abstract RU 2049798 C1

FIELD: production of pigments. SUBSTANCE: method involves oxidation of metal carbonyls (e.g. octacarbonyl of cobalt, hexacarbonyl of chromium, hexacarbonyl of molybdenum) by oxygen-containing gases. The process is carried out at 40-100 C in the presence of inert gas in moving fluidized bed of scale-shaped particles, e.g. mica, aluminium and graphite. EFFECT: improves homogeneity of dyeing. 4 cl, 1 tbl
