摘要

Monodispersed haematite particles have been synthesized by two-step hydrolysis of dilute FeCl3 aqueous solution. The first step is the hydrolysis of FeCl3 solution at 70 similar to 90 degrees C, which provided beta-FeO(OH) colloidal suspension, and the second step is the transformation from beta-FeO(OH) to alpha-Fe2O3 at 100 similar to 120 degrees C via a dissolution and recrystallization process. Partial neutralization with NaOH solution promotes the hydrolysis of highly concentrated FeCl3 solutions. Particle size of alpha-Fe2O3 can be controlled by neutralization degree, and it decreases with decreasing the electrolyte concentration. [References: 16]
