Synthesis of Magnetite Nanoparticles and the Process of Forming Fe-Based Nanomaterials

摘要

the iron salt in an organic solvent, alcohol, carboxylic acid and an amine and mixing the mixture from 200 to 360 describes a manufacturing method and structure of the magnetite nanoparticle material that is heated to. The size of the particles may be adjusted by adding to the coating of iron oxide or iron salts for varying the small nanoparticles acid / amine ratio. With the present invention, the size of 2 nm to 20 nm range are obtained and a narrow size distribution magnetite nanoparticles. The invention MFe ₂ O ₄ (M = Co, Ni, Cu, Zn, Cr, Ti, Ba, Mg) other iron oxide based nano comprising nanomaterial particle material, and iron can be easily extended to nanoparticles coated with an oxide material. The present invention can be also synthesized iron sulfide base nanoparticle material by replacing the alcohol in the reaction mixture as a thiol. Magnetite nanoparticles are -Fe ₂ O ₃ or -Fe ₂ O ₃ as oxidation or bcc -Fe can be reduced to the nanoparticles, iron oxide base material is CoFe, 2 iron base metal nanoparticles, such as NiFe and FeCoSm _x may be used in the manufacture of the nanoparticles.
