Abstract
The invention relates to an antibacterial borosilicate glass having the following composition in relation to an oxide base: 40-80 mass % SiO2, 5-40 mass % B2O3, 0-10 mass % Al2O3, 0 30 mass % P2O5, 0-25 mass % Na2O, 0-25 mass % K2O, 0-25 mass % CaO, 0-15 mass % MgO, 0-15 mass % SrO, 0-15 mass % BaO, 0-30 mass % ZnO, 0-5 mass % Ag2O, 0-10 mass % CuO, 0-10 mass % GeO2, 0-15 mass % TeO2, 0-10 mass % Cr2O3, 0-10 mass % J, 0-10 mass % F. The percentage sum ZnO+Ag2O+CuO+GeO2+TeO2+Cr2O3 +B203 ranges from 5 to 70 mass %.
