Paper Title:
Influence of Dynamic Flow Speed on Bonelike Apatite Formation in Porous Calcium Phosphate Ceramic in RSBF
  Abstract

A revised dynamic immersion device was designed, and the effects of flowing speed of SBF in inner pores of ceramics on the formation of apatite in the pores were investigated in this study. The results showed some crystals were overlaid on the walls of inner pores. The crystal shape changed with flow rate of RSBF. When flow rates of RSBF were 2 ml/min, some stamen-like crystals formed on the inner walls of ceramics. In the ceramics in RSBF with flow rate of 5ml/min, besides more stamen -like crystals, a thin layer of fine deposits was overlaid on the walls of inner holes and the surface of the stamen -like crystals. But when the flow rate was 8 ml/min, only a thick layer of fine deposits on the walls of inner pores could be found. Energy dispersive spectroscopy (EDS) and Fourier Transform Infrared spectroscopy (FTIR) results revealed the deposits obtained in this study are carbonate hydroxyapatite (CHA).
