    摘要: Glass-based substrates are described herein that may be processed by methods including applying a cover article onto a glass-based substrate, submerging the glass-based substrate in an etchant, and maintaining the submersion of the glass-based substrate in the etchant. The glass-based substrate may include a covered surface portion and an exposed surface portion. At least a portion of the covered surface portion may be in direct contact with the cover article. The covered surface portion may not be in contact with the etchant and the exposed surface portion may be in direct contact with the etchant. The etchant may contact the exposed surface portion and the cover article fora time sufficient to etch the exposed surface portion. The cover article may provide a barrier between the etchant and the covered surface portion for the entirety of the submerging.

    摘要: Methods of making a bioactive glass fiber include forming a melt of a glass composition including: 50 to 70% SiO2; 0.1 to 10% Al2O3, 5 to 30% Na2O, 0.1 to 15% K2O, 0.1 to 15% MgO, 0.1 to 20% CaO, and 5 to 10% P2O5, based on a 100 wt % of the glass composition. The melt has a viscosity of from 200 Poise to 2,000 Poise. Methods include drawing the melt into a drawn glass fiber. Bioactive glass compositions include: 60 to 70% SiO2; 15 to 30% Na2O, 5 to 15% K2O, 1 to 10% CaO, and 5 to 10% P2O5, based on a 100 wt % of the glass composition.
