Degradation Behavior of β-Ca3 (PO4)2/β-Ca2P2O7 Bioceramics
β-tricalcium phosphate (β-TCP) added with certain amounts of β-calcium pyrophosphate (β-CPP) was prepared. Degradation behavior of β-TCP/β-CPP ceramic was tested by soaking in Tris solution for 20d. The morphologies of composites before and after degradation were observed by SEM. The weight loss was tested after soaking in immersion solution. The results showed that the β-TCP/β-CPP ceramic had great potential as a biodegradable bone substitute.
