Fabrication of porous hydroxyapatite by foam technique

摘要

To improve healthcare, there is an increasing demand for bone replacement or bone graft materials towards treating and improving available parts of human body. Beside bioactive and biocompatible, synthetic hydroxyapatite can be produced with a porous structure to meet the requirement as a bone graft materials. In this work, the foam burnout technique was successfully used to produce porous hydroxyapatite. A polyurethane foam was soaked in a slip prepared by mixing hydroxyapatite powder with a binder solution prepared from polyvinylpyrolidone (PVP).
