摘要：

The aim of this work was to evaluate the effect of the two-step sintering process on consolidation of fluoridated hydroxyapatite (FHA). In addition, the effect of fluorine content on sinterability, mechanical properties, and bioactivity of FHA bulks was studied. Nanostructured FHA bulks were obtained under the conditions of 1000 and 900 degrees C for the initial and secondary temperatures, respectively, without any structural decomposition. In addition, by increasing the fluorine content, the sinterability of FHA bulks was decreased and the hardness of FHA bulks was improved. Moreover, FHA bulks showed acceptable bioactivity.
