Description of key information

No reference data are available for the density of iron pellets so the density has been assessed by read-across of density data for di-iron trioxide (Fe2O3) and calculated density of iron sinter. The rationale for this is based upon the fact that Iron pellets typically contain >90% di-iron trioxide (Fe2O3) and therefore the density will be similar to, but lower than, that of the pure oxide (5.25 g/cm3). Accordingly, it is estimated by read-across that the density of iron pellets will be approximately 5 g/cm3.
