(54) PROCESS OF WINNING OF IRON-CARRYING OXIDE MATERIALS
(57)
FIELD: chemical industry, production of structural materials, filling agents, catalysts. SUBSTANCE: iron-carrying powders are mixed with aluminum-and/or zirconium- carrying powders. Mixture is extruded, dried and subjected to treatment with laser radiation in region of focusing of CO2 - laser with wave length 10.6 m. Power density of laser radiation is 1.4-135.0 kW/sq cm, pressure of inert gas in plant amounts to 0.4- 1.4 atm. Starting powders can be produced by method of precipitation of components with subsequent thermal treatment at 500-850 C. Produced single-phase iron-oxide material has high dispersity. EFFECT: enhanced efficiency of proposed process. 1 cl, 1 dwg, 1 tbl
