REAL TIME MONITORED SYNTHESIS OF ULTRA LOW COERCIVITY MAGNETIC NANOPARTICLES WITH NARROW SIZE DISTRIBUTION

摘要

A process for the production of magnetic nanoparticles on a continuous basis from aqueous salt solutions, utilizes very rapid mixing of the reaction components to achieve particles with a uniform size and shape as well as narrow size distribution. The process includes a methodology to determine the necessary experimental conditions to achieve a sufficiently rapid mix of the reaction components, based on real-time measurements of the magnetic susceptibility of the precipitate during the precipitation reaction.
