Title: A New Method of Prepared Uniform α-Fe_2O_3 Ultrafine Powder in Solution
Abstract: In this paper,the uniform submicrometer α-Fe 2O 3 particles are prepared by the forced hydrolysis method of boiling reflux from FeCl 3 or Fe(NO 3) 3 solution,pH=4.0~4.5 for 20h.When slight amount Na 2SO 3 had been added to reaction solution,the time of completely being turned into α-Fe 2O 3 particles from Fe 3+ salts decreased to a few hours.All samples were characterized by using XRD and TEM.
