Preparation and Characterization of ß-Tricalcium Phosphate via Wet Mechanochemical Treatment


Article Preview

In this work, a simple, reproducible and low-cost synthesis method for the preparation of ß-tricalcium phosphate (ß-TCP) was developed. ß-TCP was prepared via wet mechanochemical treatment using calcium oxide and calcium hydrogen phosphate as raw materials. XRD and FTIR analysis indicated that the as-treated precursor was non-stoichiometric, poorly-crystallized carbonated hydroxyapatite (CHA) resulting from the mechanochemical reaction, and the crystalline ß-TCP powder was obtained by calcining the precursor at 800°C for 2 hours. SEM observation showed that the addition of surfactants could eliminate the agglomeration of the powder and well-dispersive ß-TCP powder with a particle diameter between 0.1 and 2.0 2m can be obtained.
