Fe2O3 specific surface area (SSA) (triangles), corresponding particle diameter (dBET, circles), and crystal size (dXRD, diamonds) as a function of FSP liquid precursor to dispersion O2 flow ratio. Increasing ratios increase particle concentration and high temperature particle residence time resulting in large primary particles and crystals.
