Preparation and characterization of porous hydroxyapatite through polymeric sponge method

Porous hydroxyapatite samples were prepared via polymeric sponge method using commercial hydroxyapatite (HA) powder. The effects of sintering rate, stirring time and HA concentration on porosity, compressive strength and crystallinity of the porous bodies were evaluated. The study found that a faste...
