Embodiment 1

[0021] Add 1.36g of sodium dodecylsulfonate into 20ml of deionized water, heat to 60°C and stir to dissolve completely, and obtain a sodium dodecylsulfonate solution with a concentration of 0.25mol / L. Weigh 8.109g FeCl 3 ·6H 2 O was added into 100ml of deionized water and stirred thoroughly to obtain a 0.3mol / L ferric chloride solution. 3 ml of sodium dodecylsulfonate solution were then added dropwise with stirring. Then, 50 ml of 0.3 mol / L NaOH solution was added dropwise under stirring, and stirred again for ten minutes to obtain a red transparent solution. The solution obtained above was transferred to a polytetrafluoroethylene-lined reaction kettle, and reacted at 170°C for 8 hours to obtain a reddish-brown precipitate of iron oxide. The product after the hydrothermal reaction was filtered, washed three times with deionized water and ethanol, and then dried at 110° C. to obtain a reddish-brown iron oxide powder. The reddish-brown iron oxide powder was calcined at 400°C...

[0023] Add 1.36g of sodium dodecylsulfonate into 20ml of deionized water, heat to 60°C and stir to dissolve completely, and obtain a sodium dodecylsulfonate solution with a concentration of 0.25mol / L. Weigh 16.218g FeCl 3 ·6H 2 O was added into 100ml of deionized water and stirred thoroughly to obtain a 0.6mol / L ferric chloride solution. Then 5 ml of sodium dodecylsulfonate solution were added dropwise with stirring. Then 100 ml of 0.3 mol / L NaOH solution was added dropwise, and stirred again for ten minutes to obtain a red transparent solution. The solution obtained above was transferred to a polytetrafluoroethylene-lined reaction kettle, and reacted at 180° C. for 6 hours to obtain a reddish-brown precipitate of iron oxide. The product after the hydrothermal reaction was filtered, washed three times with deionized water and ethanol, and then dried at 110° C. to obtain a reddish-brown iron oxide powder. The reddish-brown iron oxide powder was calcined at 350°C for 1 hour ...

Abstract

The invention belongs to the technical field of inorganic materials, and relates to a micron football-shaped iron oxide material and a preparation method thereof. In the present invention, ferric chloride hexahydrate is used as iron source, sodium dodecylsulfonate is used as surfactant, hydrothermal reaction is carried out under alkaline conditions to prepare initial powder of iron oxide material, and finally thermal roasting treatment is carried out to obtain rugby ball-shaped iron oxide powder material. The micron-sized rugby ball-shaped iron oxide material prepared by the present invention is single-phase α-Fe2O3, the major axis diameter is 1.5-1.9 microns, the short-axis diameter is 0.9-1.4 microns, the particles are dense and non-porous, the specific surface area is small, and the particle size and shape are uniform , good dispersion. It is suitable for magnetic materials, catalysts, analytical reagents, polishing materials, battery materials, red pigments, colorants, functional coatings, gas sensitive materials for gas sensors and other fields.

Description

technical field [0001] The invention belongs to the technical field of preparation of inorganic materials, in particular to a micron rugby ball-shaped iron oxide material (α-Fe 2 o 3 ) preparation method. Background technique [0002] Iron oxide is an important magnetic material, catalyst, polishing material, battery material, red pigment, colorant, functional coating, and gas-sensitive material. Widely used in telecommunications, instrument industry, paint, rubber, plastic, cosmetics, enamel, leather, magnetic alloy, catalytic industry and gas sensor and other fields. [0003] At present, the preparation methods of iron oxide micron particle materials are mainly dry method and wet method. The dry method usually uses nitric acid to react with iron flakes to form ferrous nitrate, which is crystallized by cooling, dehydrated and dried, ground and calcined, then washed with water, dried and crushed to obtain iron oxide. The wet method is to quickly react a certain amount of...
