Thermodynamic model and surface-active components of barium crystal glass

Popis výsledku v původním jazyce

The surface tension of fifteen glass-forming melts was measured by sessile drop profile analysis. The glass compositions were based on barium crystal glass [(10.49 Na2O center dot 2.36 K2O center dot 9.06 CaO center dot 0.78 ZnO center dot 2.44 BaO center dot 0.85 Al2O3 center dot 74.02 SiO2) mol%] and were changed by increasing and decreasing of the each oxide content. The drop profiles were recorded at 1190 degrees C and analyzed by the numerical integration of Laplace&apos;s equation using the experimentally determined melt density. The results show that the increasing content of Na2O, K2O, ZnO, Al2O3 and SiO2 significantly decreases the surface tension. The Shakhmatkin and Vedishcheva thermodynamic model (TDM) was used to describe each glass melt at 1190 degrees C. 57 components were considered in the TDM, but only 25 components were present in non-negligible equilibrium amounts. Multilinear analysis was used to determine the surface-active components, i.e., components that decrease the surface tension. The analysis was performed using the dependence of surface tension on the equilibrium molar amounts of non-negligible and statistically independent components of the TDM.
