Abstract

Correlations between the wettability of Pt with molten silicate and polarization potential \varphi were investigated in argon atmosphere at 1073 K. The following results were obtained. (1) The wettability is improved remarkably with the anodic polarization before hysteresis of contact angle θ versus \varphi appears. (2) In the case of anodic polarization, the correlations between θ and \varphi for PbO-SiO2 melts show smooth curves that have a maximum in the case of SiO2≤33%. In the case of SiO2≥40%, the θ-\varphi curves show a shelf-like form. The width of the shelf increases with increasing SiO2 content. (3) Addition of K2O to PbO-SiO2 (40%) melt shows a tendency to promote the action of PbO on the θ-\varphi curve.
