Porous hydroxyapatite ceramics of bi-modal pore size distribution.

摘要: A route for the fabrication of porous hydroxyapatite ceramics having two populations open pores is reported. The bodies are prepared by sintering spherical gelatin/hydroxyapatite granules. As result, containing intragranular small-size and intergranular large-size interconnecting obtained. pore size content dependent on route. Ceramics can generally be applied as bone replacement materials where interconnections in pathway to conduct cells vessels ingrowth, whereas filled with a drug, e.g. eliminate infections.
