| 摘要 |
<p>A bioactive glass composition comprises (wt.%) 51-56% silicon oxide, 7-9% sodium oxide, 21-23% calcium oxide, 10-12% potassium oxide, 1-4% magnesium oxide, 0.5-1.5% phosphorus pentoxide, and 0-1% boron oxide. An independent claim is also included for a method of manufacturing heat-treatable bioactive glass composition comprising heating a mixture of starting materials to 1350-1450[deg]C for 3 hours allowing the obtained melt to cool down to ambient temperature for >=12 hours; crushing the obtained solid glass into pieces; reheating the crushed glass material to 1350-1450[deg]C for 3 hours; and molding the obtained bioactive glass composition into desired shape and allowing it to cool down to ambient temperature.</p> |
