The activity coefficient of strontium in a copper melt has been investigated by a chemical equilibrium technique in the temperature range from 1473 to 1773 K. A graphite crucible was used to control the oxygen partial pursuer in CO gas. The activity coefficient was derived from the standard free energy of formation of SrO, the oxygen partial pressure, and the concentration of strontium in copper. The standard free energies of formation for SrO·DAl2O3 and SrO2·Al2O 3 at 1723 K are also derived by equilibrating Al2O 3, SrO·6Al2O3, and SrO·Al 2O3 with Cu.
