ABSTRACT:
Disclosed are glass compositions and glass fibers formed from certain embodiments of the disclosed glass compositions. Certain embodiments of the glass compositions include, among other components, bismuth oxide. Certain embodiments of the glass composition include about 0.5–30% bismuth oxide of the composition by weight and silica oxide at about 54–70% of the composition by weight. Embodiments of the glass compositions may also include other components. For example, zinc oxide can make up about 0.01–5% of the composition by weight.
