A novel sol-gel technique for hydroxyapatite preparation

The concept of biocompatible, osteoconductive material mimicking the structure of natural bone to be used as bone graft has generated a considerable interest in recent decades. This paper reports on a novel and simple sol-gel technique for fabricating pure hydroxyapatite powder. Compositional, microstructural, morphological and mechanical characterisations carried out on the powder as well as on dense and porous sintered bodies, are also reported.
