Preparation and characterization of macroporous bioactive glass ceramic made via sol-gel route and powder sintering method

The purpose of this study was to prepare macroporous glass ceramic scaffold by sol-gel glass synthesis and powder sintering method. Sodium nitrate was added during sol-gel process to obtain glass ceramic with mol composition of 42.11% SiO2 - 18.42% CaO - 29.82% Na2O - 9.65% P2O5. The glass particles...
