Abstract

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

摘要

通过在800℃下加热具有不同结构的无定形磷酸钙前驱体3小时，成功合成了由α-磷酸三钙（α-TCP）和β-磷酸三钙（β-TCP）组成的新型可生物降解双相磷酸三钙（BTCP）。在无定形前驱体合成过程中，磷酸钙颗粒中α-TCP和β-TCP的比例可通过老化时间和pH值来控制。
