Precipitation of Calcium Phosphate at pH 5.0 for the β Tri-calcium Phosphate Cement

The purpose of this study was to prepare calcium phosphate cement [CPC] for use in artificial bone. Nano-crystalline calcium phosphate [CaP] was precipitated at $37^{circ}C$ using highly active $Ca(OH)_2$ in DI water and an aqueous solution of $H_3PO_4$. From the XRD measurements, the nano-CaP powder was close to apatitic TCP phase and the powders fired at $800^{circ}C$ showed a critical ${beta}$-TCP phase. A mixture of one mole $CaCO_3$ and two moles di-calcium phosphate was calcined at $1100^{circ}C$ to make a reference ${beta}$-TCP material. The nano-CaP powders were added to the normal ${beta}$-TCP matrix and fired at $900^{circ}C$ to make a ${beta}$-TCP block. The sintered block showed improved mechanical strength, which was caused by the solid state interaction between nano-CaP and normal ${beta}$-TCP.
