Influence of α-Tricalcium Phosphate Crystallinity on Cement Formation

Calcium phosphates have been used in orthopaedic surgery for several decades. Due to their similarity to the natural bone, calcium phosphate cements (CPC) are able to successfully adapt to the body as well as integrate into the bone structure, filling bone defects. Different level of reactant crystallinity made by synthesis and heat treatment have not yet been investigated for the influence on the rate of cementation. Our goal is to produce porous calcium deficient hydroxyapatite from the hydrolysis of tricalcium phosphate using source materials with a different crystallinity. Alfa tricalcium phosphates (α-TCP) when mixed with water undergoes the following hydrolysis reaction: 3α-Ca3(PO4)2 + H2O→ Ca9(HPO4)(PO4)5OH
