摘要

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, increased indentation toughness in most cases, and promoted microcracking when sintered at high temperatures. The addition of BG could either strengthen or weaken HA, depending on the BG content and sintering condition. Practically, the optimal properties were obtained from the HA doped with 2.5 wt.% BG sintered at 1250°C.
