Removal of Chloride Ions in [alpha]-Fe2O3 by Heating in Humid Air
Chloride ion contained in α-Fe2O3 powders has been effectively removed by heating in humid air without any changes in the surface areas of the powders. The Cl- content in α-Fe2O3 decreased to O.10-0.045 wt% by heating at 300-560°C for 1.0 h in the air containing 28 wt% H2O. The treated α-Fe2O3 revea...
