Seed-mediated Generation of Epsilon Iron Oxide Nanocrystals at 300 °C

Epsilon iron oxide (c-Fe2O3) is a material with a high coercive field. Herein we report seed-mediated generation of c-Fe2O3. The generation of c-Fe2O3 can be accelerated with the calcination of Prussian blue (PB) by a proliferative reaction, using c-Fe2O3 nanoparticles as a seed. The present synthetic reaction occurs at a temperature below 300 degrees C, suggesting this is a promising method for low-temperature synthesis of c-Fe2O3.
