Preparation and characterization of super-paramagnetic Fe304 nanoparticles
摘要
Abstract
Objective To prepare super paramagnetic Fe3O4 by hydrothermal method and test the physical and magnetic properties. Methods The Fe3O4 nanoparticles with PEG6000-coating is obtained by means of hydrothermal method, the structure is analyzed by X-ray powder diffraction method, the size and distribution is measured by transmission electron microscope, and the susceptibility is measured by Vibrating Sample Magnetometer dollars. Results The particle diameter size of the super paramagnetic Fe3O4, is 200 nm. These particles possess some characteristics of super paramagnetism. The quality saturation magnetic intensity is 79.8emu/g Fe. Conclusions The samples are dispersed, water-soluble,super-paramagnetic and homogeneous in particle diameter, which can be used in physical chemistry thrombolysis.关键词
