Novel highly biodegradable biphasic tricalcium phosphates composed of α-tricalcium phosphate and β-tricalcium phosphate

Novel biodegradable biphasic tricalcium phosphates (BTCP) composed of α-tricalcium phosphate (α-TCP) and β-tricalcium phosphate (β-TCP) were successfully synthesized by heating amorphous calcium phosphate precursors with different structures at 800 °C for 3 h. The ratio of α-TCP and β-TCP in the calcium phosphate particle can be controlled by aging time and pH value during synthesis of the amorphous precursor.
