International audienceIn bone tissue engineering, ceramics are widely used as implant material to enhance bone growth formation or as drug release vehicle. In the existing work porous Hydroxyapatite scaffolds were prepared by polymeric replication method using Cellulose as a binding agent. The influence of binder on various sintering temperature were evaluated. The Hydroxyapatite scaffold sintered at 1150°C was characterized for phase purity, structural analysis and porosity measurements. Hence, it is possible to produce Hydroxyapatite scaffolds with highly inter connecting macro and micro pores with an apparent density of 0.944g/cm 3 corresponding to 75% porosity
