In vitro Dissolution Behavior of Biphasic Tricalcium Phosphate Composite Powders Composed of α-Tricalcium Phosphate and β-Tricalcium Phosphate

摘要：

　　Biphasic tricalcium phosphate (BTCP) powders composed of α-tricatcium phosphate (α-TCP) and β-tricalcium phosphate (β-TCP) were prepared using amorphous calcium phosphate (ACP) precursor after heat treatment at 800℃.The in vitro dissolution behavior of the powders was examined after soaked in 0.1M NaAc-HAc buffer solution for different times.It was revealed that the Ca2+ and PO43-concentration,and pH value of the BTCP-soaked solution are higher than those of the α-TCP-and β-TCP-soaked solutions.The dissolution behavior of BTCP powders was explained.The specific dissolution behavior of BTCP powders can widen the biodegradation range of calcium phosphate family.
