Résumé

The solubility of chromium oxide (Cr2O3) in soda lime silicate glasses was studied as a function of temperature (1,200 A degrees C a parts per thousand currency sign T a parts per thousand currency sign 1,350 A degrees C), oxygen fugacity (-12 a parts per thousand currency sign log fO(2) a parts per thousand currency sign -0.6) and glass composition (Na2O-CaO-xSiO(2); x = 3, 4, 5 and 6). The fO(2) was proved to induce several oxidation states of Cr for a given glass composition at a fixed temperature. The influence of glass composition on the Cr solubility was interpreted in terms of the optical basicity I > concept. An increase in the melt basicity led to an increase in the Cr solubility for the experiments conducted under oxidizing conditions. The total dissolved Cr also showed a significant increase with increasing temperature for a given fO(2) and glass composition. The results proved that the stability of Cr2O3 scale against corrosion was profoundly influenced by fO(2), T and melt basicity.
