A novel method for the production and characterization of calcium phosphate biomaterials

The sinterized hydroxyapatite is characterized by high crystallinity that makes it difficult to integrate in the bone turnover. The paper proposes (i) a new method to prepare calcium phosphate manufacts characterized by a low crystallinity, and (ii) a new method to characterize the microstructure and composition of hydroxyapatite. The characterization method pointed out is based on measurement techniques used for civil engineering materials. Therefore, it is possible to assess that the obtained results depend only by the material under test and not by the specific measurement method. Experimental results assess (i) the suitability of the characterization method pointed out, and (ii) the similarity among the mechanical, chemical and physical characteristics of the obtained hydroxyapatite and human bone ones.
