Abstract
A nanometre-class iron oxide powder with different shapes prepared through the reaction between Fe-ion solution and alkaline solution under the condition of introducing surfactant, and features that the shape of the said nanometre iron oxide particles can be controlled by regulating the proportion mix between the high-molecular and the low-molecular surfactants. Its advantages are fine and uniform granularity (10-30 nm), simple equipment and low cost.
Description
Technical field
The present invention relates to the manufacture method of nano material, the manufacture method of especially difform alpha-iron oxide nano-powder.
Background technology
Nano material is the novel material that development in recent years is got up, and demonstrates purposes and special excellent effect widely in each field.Because technology limitation, the iron oxide particles granularity of making also fails to reach nano level at present, does not far reach the production scientific research requirements.Application number is the manufacture method that 99114908 Chinese invention patent application discloses a kind of nanometer cobalt oxide, it is characterized in that in chemical precipitation method, introducing tensio-active agent, the cobalt oxide granularity that produces reaches 5～60nm, but this method will be carried out under heating, thereby the production unit requirement is high, and cost improves greatly.
Summary of the invention
Purpose of the present invention will provide a kind of working condition requirement simple exactly, can generate difform, product granularity is little and the manufacture method of uniform alpha-iron oxide nano-powder.
For reaching above-mentioned purpose, the method that the present invention makes alpha-iron oxide nano-powder is as follows:
A, employing or the preparation ferrous ion aqueous solution;
B, preparation basic solution;
C, ferric ion solutions and basic solution react under the condition of introducing tensio-active agent, and reaction is carried out at normal temperatures and pressures;
D, resultant washing, oven dry.
Described basic solution can be sodium hydroxide, potassium hydroxide or ammoniacal liquor.
Described tensio-active agent is that low-molecular-weight surfactant and polymeric surface active agent are used, consumption be iron in the raw material weight percent 0.1～18%.
Described low-molecular-weight surfactant is at least a in Sodium dodecylbenzene sulfonate, stearic acid oxygen Vinyl Ether series, alkylphenol polyoxyethylene class, fatty acid loss water sorbit ester class or the arlacels, and described polymeric surface active agent is at least a in polyvinyl alcohol, silicone oil, polyacrylamide, polyoxyethylene glycol, the polyacrylic acid.Low-molecular-weight surfactant and polymeric surface active agent consumption proportion are to obtain the styliform nano ferric oxide at 6～15: 0.1～3 o'clock, and proportioning is to obtain the ball shaped nano ferric oxide at 6～15: 0.1～2 o'clock.
Adopt manufacture method of the present invention, the particle diameter of ferric oxide powder reaches 10～30nm, and granularity is tiny evenly; Adjust the proportioning of dosage of surfactant, can obtain difform alpha-iron oxide nano-powder; Reaction is carried out at normal temperatures and pressures, and production unit requires simple.
