The viscosities of Li2O-SiO2-Ga2O3 and BaO-SiO2-Ga2O3 melts were measured in order to clarify the behaviour of M2O3 in the composition range of molar ratio M2O3/MeO>1, and the viscosity data on each gallosilicate were arranged using the parameter Pη (1) and Pη (2) corresponding to the composition ranges of molar ratio M2O3/MeO≤1 and M2O3/MeO≥qq1, respectively.
The parameter Pη (1) and Pη (2) are expressed by
viscosity, amphoteric oxide, aluminosilicate, gallosilicate, coordination of Al3+ and Ga^3+ ions
