Abstract

The solubility of platinum in the molten BaO-Al2O3, BaO-SiO2, CaO-Al2O3, CaO-SiO2, Na2O-SiO2, and CaO-Al2O3-SiO2 systems has been measured in order to seek a new measure of basicity. The solubility of platinum increases with increasing content of basic oxide. The correlations among the solubility of platinum, carbonate, sulfide, and phosphate capacities, basic oxide activities, and theoretical optical basicity are discussed.
