摘要：
We tried to confirm the conversion of Ca3P2 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 Ca3P2 was converted to beta-3CaO center dot P2O5 and 4CaO center dot P(2)O5 phases by oxygen injection treatment of the molten RDP slag by XRD analysis and thermodynamic estimation.
