Abstract

Nano-bioactive-glasses have been prepared by a quick alkali-mediated sol–gel method. The gelation time was around 2 min. The size of bioactive glasses could be controlled via addition of ammonia solution. The TEM images showed that the NBG particles size were 20–40 nm using 1 M ammonia solutions. TG-DSC curves indicated that the organic and inorganic precursors have been decomposed completely before 550 °C. WAXRD pattern of NBG calcined at 600 °C in air confirmed that the calcined glass generally existed in amorphous state.
