The viscosity of liquid albite (NaAlSi3O8) has been determined over the temperature range 800-1000°C. The results are combined with data obtained at higher temperatures to obtain the overall log η versus 1 T relation. The relation indicates Arrhenian behavior, with an apparent activation energy of ∼95 kcal mol-1. By comparing the viscous flow behavior of albite with that of the other materials, including SiO2, GeO2 and B2O3, it is suggested that liquid albite is a random network of SiO4 and AlO4 tetrahedra.
