| Abstract: | In the present research,surface tension and density of borosilicate melts were measured and compared to that of Na-Ca containing glass melt using sessile drop method. The results show that the density of borosilicate melt,always lower than that of Na-Ca containing glass melt,decreases linearly with temperature rising. The temperature dependence of density indicates a lower thermal expansion coefficient of borosilicate melt. The surface tension of both borosilicate and Na-Ca containing glass melts increases ... |
