A biocompatible glass which can be melted using infra-red radiation contains, based on oxide, 65-68% by weight of SiO2, 0-3% by weight of Li2O, 12-14% by weight of Na2O, 2.5-4% by weight of K2O, 15-17% by weight of SIGMA alkali metal oxides, 2-3% by weight of MgO, 4.2-5.5% by weight of CaO, 0-2% by weight of BaO, 3-4 % by weight of Al2O3, 0-1.0 by weight of B2O3 and 2.7-4.1% of FeO. The glass, due to its infra-red meltability and its physiological accertability, is suitable for the encapsulation of sensitive materials, such as transponders or minitransmitters, which are implanted in a living body, or as ampoule glass for melt-encapsulation of sensitive substances.
