抄録

From a critical review of the existing experimental data, the free energy equations are presented. A new estimate is made of the standard free energy of formation of the hypothetical pure liquid P<sub>2</sub>O<sub>5</sub>, which is used in calculating the P<sub>2</sub>O<sub>5</sub> activity coefficients from the experimental data of independent studies of slag–metal reactions. It is found that in low P<sub>2</sub>O<sub>5</sub> slags, log( γ<sub>P<sub>2</sub>O<sub>5</sub></sub>) is a linear function of CaO from 0 to 60%, independent of temperature. Whereas, in slags containing P<sub>2</sub>O<sub>5</sub> > 10%, log(γ<sub>P<sub>2</sub>O<sub>5</sub></sub>) is a linear function of CaO content > 40% only and increases with an increasing temperature. A novel concept of a slag–P<sub>2</sub>O<sub>5</sub> emf sensor is presented for experimental evaluation.
