Abstract: |
|||
| Glass compositions useful for forming fibers which are readily able to be degraded in a physiological medium such as that found in a human body. Advantageous compositions formed according to the present invention comprise the following components, set forth in percent by weight: SiO2: 57 to 70% Al2O3: 0 to 5% CaO: 5 to 10% MgO: 0 to 5% Na2O K2O: 13 to 18% B2O3: 2 to 12% F: 0 to 1.5% P2O5: 0 to 4% Impurities: less than 2%. | |||
