Title:
マグネタイト・ナノ粒子の合成および鉄をベースとするナノ材料形成方法
Document Type and Number:
Japanese Patent JP3989868
Kind Code:
B2
Abstract:
A method and structure for making magnetite nanoparticle materials by mixing iron salt with alcohol, carboxylic acid and amine in an organic solvent and heating the mixture to 200-360° C. is described. The size of the particles can be controlled either by changing the iron salt to acid/amine ratio or by coating small nanoparticles with more iron oxide. Magnetite nanoparticles in the size ranging from 2 nm to 20 nm with a narrow size distribution are obtained with the invention.
