SILICONE DOPED CALCIUM PHOSPHATE POWDER SYNTHESIZED VIA HYDROTHERMAL METHOD

Synthetic pure hydroxyapatite have excellent biocompatibility and a little osseous inductivity, however, there are still some shortcomings such as the high degree of crystallinity and the quite stability of the structure. It is known also that Si is incorporated in biological body and improved bone remodeling. 0.5, 1, 2, 5 and 10% mol Si dope have been attempted to incorporate in calcium phosphate trough hydrothermal synthesis method. After calcination of 700ºC Ca-deficient hydroxyapatite transformed to octacalcium phosphate for 2 and 5% Si only while the others transformed to β-tricalcium phosphate. Crystallinity of the samples reduced with Si mol increases and calcination temperature increases as well
