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

摘要：

　　In this work,a simple,reproducible and low-cost synthesis method for the preparation of β-tricalcium phosphate (β-TCP) was developed.β-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 β-TCP powder was obtained by calcining the precursor at 800℃ for 2 hours.SEM observation showed that the addition of surfactants could eliminate the agglomeration of the powder and well-dispersive β-TCP powder with a particle diameter between 0.1 and 2.0 μm can be obtained.
