COMPOSITION, USE AND MANUFACTURE OF BIOACTIVE GLASS

摘要

The invention relates to a bioactive glass composition comprising SiO2, Na2O, CaO, K2O, MgO, P2O5 and B2O3. According to the invention, the amount of SiO2 is 51-56 wt-% of the starting oxides, Na2O is 7-9 wt-% of the starting oxides, CaO is 21-23 wt-% of the starting oxides, K2O is 10-12 wt-% of the starting oxides, MgO is 1-4 wt-% of the starting oxides, P2O5 is 0,5-1,5 wt-% of the starting oxides, B2O3 is 0-1 wt-% of the starting oxides, provided that the total amount of Na2O and K2O is 17-20 wt-% of the starting oxides. The invention further relates to the use of said bioactive glass composition and the manufacturing of said bioactive glass composition.
