Abstract

The phase relation of the system ZrO2+BaO+P2O5 was investigated at 1673K. Seven compatibility triangles were detected, ( 1 ) BaO·ZrO2+3BaO·P2O5+10BaO·3P2O5, ( 2 ) ZrO2+BaO·ZrO2+3BaO·P2O5, ( 3 ) ZrO2 +3BaO·P2O5+7BaO·ZrO2·3P2O5, ( 4 ) ZrO2+7BaO·ZrO2·3P2O5+BaO·ZrO2·P2O5, ( 5 ) ZrO2+BaO·ZrO2·P2O5+BaO·4ZrO2·3P2O5, ( 6 ) ZrO2+ZrO2·2P2O5+ZrO2·P2O5, ( 7 ) ZrO2·P2O5+ZrO2·P2O5+BaO·4ZrO2·3P2O5. In addition to the phase diagram studies, the electrical conductivities of ZrO2+14.55 mol% BaO+3mol%P2O5 electrolyte were measured to find a suitable three-phase electrolyte for rapid determinations of phosphorus in hot metal.
