Animal origin hard tissues represent alternative raw materials that can be used for the fabrication of calcium phosphates based products with applications in orthopedics and dentistry. The methods of obtaining calcium phosphates from this kind of biological precursors (constituting sustainable and inexpensive resources) can determine the characteristics of the final products. 

In this chapter, the main influences of temperature on the products obtained by hard tissues thermal processing are presented, highhghting the approaches and methods available nowadays. The main thermal analysis methods used to trace/identify the transformations that occur with the increase of the fabrication temperature are also emphasized. The correlation of such results with ones provided by complementary investigation methods, such as scanning electron microscopy, energy dispersive X-ray spectroscopy or X-ray diffraction, can enable a complex and insightful research on the evolution of the morphology and structure of hard tissues when subjected to heat-treatments. In the final part, results obtained for thermally treated bone samples are presented and an ample comparative discussion is carried out with respect to other reported studies.
