摘要

We tried to confirm the conversion of Ca_3P_2 to calcium phosphate by oxygen injection into the molten Reducing Dephosphorization (RDP) slag as well as to find the stoichiometry of calcium phosphate compound by the treatment. It was experimentally confirmed that the Ca_3P_2 was converted to beta-3CaO·P_2O_5 and 4CaO·P_2O_5 phases by oxygen injection treatment of the molten RDP slag by XRD analysis and thermodynamic estimation.
