| Abstract: | Single crystalline α-Fe2O3 cubic particles of narrow size distribution were prepared by a hydrothermal synthesis at 130 °C from a solution of urotropine ((CH2)N4) and ferric chloride. About 400 nm faultless cubic particles were observed. Spheres with rough surface were synthesized at 80 °C, while pseudo cubes and some spheres were prepared at 100 °C. For the preparation of α-Fe2O3 cubes, 130 °C is the appropriate temperature. |
