The aim of the paper was to obtain a porous hydroxyapatite (HA) biomaterial
s relating to the manufacture of artificial implants. The technique of impr
egnating a body of porous polyurethane foam with slurry containing HA powde
r, water and additives was applied and proved to be more successful. The pr
ocess of preparations was discussed and the porous HA with desired properti
es was obtained at last. (C) 2001 Kluwer Academic Publishers.
