METHOD OF PRODUCING IRON-CONTAINING PIGMENT FOR CERAMICS Russian patent published in 2025 - IPC C09C1/24 C09C3/04 C04B14/30 

Abstract RU 2841385 C1

FIELD: chemistry.

SUBSTANCE: invention can be used for volume painting of wall ceramics. To obtain an iron-containing pigment wastes from enrichment of ferruginous quartzites of the Kursk magnetic anomaly are heat treated in a plasma reactor for 1-2 s at a plasma jet temperature of 7000-7500 K. Method then includes grinding in a centrifugal-planetary mill to particle size 3.5-3.6 mcm with specific surface area 620-640 m2/kg.

EFFECT: invention speeds up production of a pigment which gives the ceramic a dark brown colour, and reduces power consumption.
