✦ Synopsis


The Ξ²-tricalcium phosphate phase, Ξ²-Ca 3 (PO 4 ) 2 , has been studied at high pressures up to 15.4 GPa and room temperature in a diamond-anvil cell using angle-dispersive X-ray diffraction. No evidence of a phase transformation was observed in the present pressure range at 300 K. By fitting the pressure-volume data to a second-order Birch-Murnaghan equation of state, the bulk modulus, B 0 , was determined to be 79.5 Β± 2.0 GPa.

The setting reactions of calcium phosphate cements in the CaHPO4-alpha-Ca3(PO4)2 (DCP-alpha-TCP) system have been investigated. X-ray diffraction (XRD) analyses were performed on DCP-alpha-TCP cement samples of varying calcium to phosphorus (Ca/P) ratios after setting for 24 h in Ringer's solution a
