    摘要: A family of radiopaque glasses comprising silicon dioxide (15-30%), ytterbium oxide (5-35%), barium oxide (30-50%) and fluoride (5-20%), all by weight. The family of glasses all exhibit high radiopacity with refractive indices varying from 1.508-1.592 and translucency ranging from clear to moderately opaque. These glasses can be incorporated into dental composites to provide radiopaque dental restoratives with a desired translucence and appearance.
