The Influence of the Chemical Composition and Temperature of Molten Rocks on Laws Wetting Their Platinum-Rhodium Plate Spinneret

Abstract

The results of investigation of platinum-rhodium substrate wetting by the melts of ten different compositions ofrocks 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, whichdo not containiron oxide compounds are characterized by a high value of the contact angle and the lowest values of surface forces. Doping of ZrO2 in the melt composition significantly increases angles of wetting and surface tension and adhesion through out the temperature range as compared with the same melts without zirconia.Keywords: silicate melt, basalt, melting, wetting, surface tension, rock.
