Abstract The present invention relates to preparation of nanometer level iron oxide red alpha-Fe2O3 and the main technological feature is that Fe(OH)3 gel is first formed through the reaction of Fe3+ solution and base and then converted at low temperature in the presence of small amount of phase conversion catalyst into nanometer level alpha-Fe2O3 grains. The preparation process uses simple equipment and has low cost.
