NOVEL FABRICATION OF POROUS HYDROXYAPATITE BY ELECTROPHORETIC DEPOSITION PROCESS

抄録

We have developed the novel and simple fabrication of porous hydroxyapatite by electrophoretic deposition (EPD) method in H₂O/ethanol system. In this study, the porous hydroxyapatite bulks through the controlled use of H₂ gas generation in the aqueous EPD process could be successfully prepared. Especially, it was found that this aqueous EPD process in combination with a sintering process could advantageously result in unique porous bulks containing unidirectionally aligned continuous pores with some hundreds μm in diameter. These unique microstructured porous hydroxyapatite prepared by EPD process will lead to the usage of porous fillers of bone etc.
