Phosphorus is introduced into iron from phosphate in the ore. Phosphates get reduced in the reducing atmosphere in the blast furnace and phosphorus is formed. This phosphorus combines with iron to form Ee 3 P. Some of the phosphorus may get oxidised too, into P 2 O 5. This oxidation of phosphorus to P 2 O 5 is an exothermic reaction and takes place at low temperature. P 2 O 5, if formed, is ...
