Abstract RU 2067921 C1

FIELD: paint-and-varnish industry, particularly, method for producing non-organic pigments, namely, dry metal white pigment from all metals suitable for producing white pigment by pyrometallurgic way. SUBSTANCE: method involves high-temperature heating of metal, oxidation in gaseous phase of its vapors, catching formed metal oxide. Novelty is realized by high-temperature metal heating at temperature higher than metal welding one and oxidation by air of scattered metal particles at temperature higher than its boiling one. EFFECT: simplified, reduced energy consumption.
