Effect of Composition on the Tendency of Forming BAS (Barium Aluminosilicate) Sintered Glass by Sol-Gel Process
Source abstract
Abstract
The effect of composition on the tendency of forming BAS (barium aluminosilicate) sintered glass with compositions near the theoretical composition of barium feldspar by sol-gel process was studied by XRD, SEM and Raman spectrum. Results indicated that, in the experimental range, larger SiO2 content and larger BaO/Al2O3 ratio were advantageous to glass formation. Increasing BaO/Al2O3 ratio causes an increase in the amount of alumina with [AlO4] structure. The relationship between [AlO4]/Al3+ and BaO/Al2O3 can be expressed as a linear equation. A criterion for glass formation in the studied system was established. The criteron showed good fitness with the experimental results.
