Effect of doped bioactive glass on structure and properties of sintered hydroxyapatite

The effects of doped bioactive glass (BG) on the structure and properties of sintered hydroxyapatite (HA) have been studied. The results showed that a calcination treatment at 900 °C increased the degree of crystallinity and the amount of hydroxyl group in HA, but resulted in the loss of a small amount of phosphorus. The addition of BG enhanced HA phase decomposition and hydroxyl group breakdown processes, decreased HA density and microhardness,...
