摘要
The viscosity-temperature characteristics of aluminosilicate glasses of R2O(RO) · Al2O3 · 6SiO2 composition, activation energy and pre-exponential factor, are reported. The complex dependence of these characteristics on the cation electronegativity is due to strong cation influence on AlO bond strength and determines viscous flow of these framework glasses. © 1990.
