N2 - The effect of composition on the glass-forming tendency of barium aluminosilicate gels derived from metal alkoxides with compositions near the theoretical composition of barium feldspar was studied. Results indicated that, in the experimental range, larger SiO2 content and larger BaO/Al2O3 ratio were advantageous to glass formation. A criterion for glass formation in the studied system was established as (b + 3 - 4y)/(2y + s(1 + b)/(100 - s)) < Jc, where b is the BaO/Al2O3 ratio, s the mol percentage of SiO2, y the fraction of four-coordinated aluminum over the total amount of aluminum, and Jc is a constant for a definite experimental condition. The criterion showed good fitness with the experimental results.
