ABSTRACT
Bone replacement is required when one suffers from bone loss as a result of disease or severe fractures. Materials for bone replacement require that they should not only possess similar characteristics as human bones but also be biocompatible. Thus, hydroxyapatite (Ca10(PO4)6(OH)2, HAp), owing to its biocompatibility and nontoxicity properties (Webler et al. 2014) has become one of the most used material for artificial bone production. Hydroxyapatite in powder form, can be used as a coating material (Surmeneva et al. 2015) and as raw material for fabricating three dimensional bone structures (Ramay & Zhang 2003).
