The results of investigation of platinum-rhodium substrate wetting by the melts of ten different compositions of rocks and the values of their surface tension and adhesion in a wide temperature range. It is shown that the highest values of surface tension and adhesion observed for basalt melts, whereas neutral aluminosilicate glass melts, which do not containiron oxide compounds are characterized by a high value of the contact angle and the lowest values of surface forces. Doping of ZrO2in the meltcompositionsignificantly increases angles of wetting and surface tension and adhesion throughout the temperature range as compared with the same melts without zirconia.
