In this work, the sintering and grain growth of hydroxyapatite green bodies are analyzed in order to identify the optimum heat treatments for the preparation of porous hydroxyapatite scaffolds. Sintering in air at temperatures ranging between 1100 and 1200 Β°C yields dense materials with narrow grain

Hydroxyapatite (HA) powder was prepared by wet chemical method. The hydroxyapatite phase was stable up to 1250 Β°C without decomposition to beta-tricalcium phosphate. Interconnected porous hydroxyapatite scaffold resembling trabecular bone structure was developed from polymeric replica sponge method.

## Abstract A novel scaffold with large dimension of 3–4 cm in length and 1–1.5 cm in diameter was designed and fabricated for engineering large bone tissue __in vivo__. The scaffold was constructed by filling hydroxyapatite (HA) spherules into a porous HA tube. The HA spherules were prepared by ch

## Abstract Pure hydroxyapatite (HAp) and a biphasic calcium phosphate [containing 90% of β‐tri‐calcium phosphate (β‐TCP) and 10% HAp] were tailored through an aqueous solution combustion synthesis. Porous struts were prepared using all the powders along with bioglass, a known bioactive material, a
