  • Aluminofluorosilicate glass
    Patent number: 6107229
    Abstract: The invention relates to an aluminofluorosilicate glass for use in a material for dental restoration, which has the following features:a) a ratio of Al (calculated as Al.sub.2 O.sub.3) to Si (calculated as SiO.sub.2) of 0.57-1.12 by mass;b) a total content of Mg (calculated as MgO) and Ba (calculated as BaO) of 29-36% by mass;c) a ratio of Mg (calculated as MgO) to Ba (calculated as BaO) of 0.028-0.32 by mass;d) a content of P (calculated as P.sub.2 O.sub.5) of 2-10% by mass.The glass according to the invention has a high radiopacity, and the refractive index n.sub.D for visible light can be adjusted by varying the phosphorus content.
