✦ Synopsis

Abstract

The magnetite nanoparticles were synthesized by different reaction conditions. The growth process of nanoparticles and influence of synthetic conditions on the particles were studied. The results show that an enough reaction time is necessary to ripen nanoparticles. However, the over‐long time leads to the deterioration of size distribution. The lower decomposition temperature is harm to size distribution. The ratio of surfactant to precursor is important for controlling nanoparticles. To attain uniform large nanoparticles, a two‐step method is reasonable method. The large iron oxide nanoparticles (up to 25 nm without agglomeration) can be produced by this method.
