Preparation of Iron Oxide Nanoparticles in Non-aqueous Solution

Abstract

Abstract: Iron oxide nanoparticles were prepared in non-aqueous solution. The nanoparticles were characterized by FTIR, XRD, TEM, TG-DTA and Mossbauer techniques. Amphous ultrafine FeOOH particles can be obtained at room temperature. Different kinds of iron oxide nanoparticles can be systhesized by controlling the calcining temperature. When calcined at 300℃ for 1h, FeOOH transformed to Fe_3-xO₄, and the Fe_3-xO₄ particles size was about 30 nm. α-Fe₂O₃ can be obtained at the temperature of 450℃ for Ih and its primary particles size increased to98nm.

Key words: non-aqueous, iron oxide nanoparticles, stearic acid, preparation
