Abstract:
Objective Bio-ceramics has been widely utilized as a common type of bone repair material.The research was designed to focus on preparation and characterization of porous TCP.Methods By using hydroxyapatite (HA) as the raw materials,and adding calcium phosphate bio-glass to adjust the ratio between calcium and phosphate,in order to achieve making porous TCP bio-ceramic scaffolds during high temperature heating process.Results Test results showed that by applying this method,TCP scaffolds had significantly higher mechanical strength then those were made from powdered TCP,and its compressive strength reached 9.11 MPa.Conclusion Tri-Calcium Phosphate (TCP) has excellent biocompatibility and it is also biodegradable.In the physiological environment,it is able to be gradually decomposed,absorbed and to promote bone growth ultimately,it is capable of replacing the damaged bone components with brand new bone tissues.
