Effect of Glass Phase on The Microstructure and Sintering Behavior of Hydroxyapatite Ceramic Composites with Controlled Pore Size

摘要

Hydroxyapatite (HAp) with controlled pore sizes was prepared with polymethly methacrylate (PMMA) as pore-making agent. Large cracks turned up in the sintered body due to the introduction of large PMMA particles. A certain kind of bio-compatible glass was applied to heal the cracks. The results show that proper glass addition could significantly improve the microstructure as well as the strength of porous HAp ceramics.
