Investigation of The Microstructures And Mechanical Properties of New Biografts As Alternative Bone Graft

In this study, alternative biografts used for orthopedic applications were produced by sol gel method. The effects of boric acid, MgO and SrBr2 compounds on the morphological structure and mechanical properties of the produced biografts were investigated. For these purposes, the morphological effects of biografts were examined by FTIR, XRD and SEM-EDX analyzes and their mechanical properties were investigated by hardness and compression tests. As a result of FTIR and XRD investigations on all biografts, it was observed that the additive materials decreased the crystallinity and formed the HA (Hydroxyapatite), β-TCP (Beta tricalcium phosphate), Ca3 (Si3O9), Ca2H4O9P2 phase structures. In addition, as a result of the SEM-EDX and mechanical tests, it has been determined that different sizes of grain structure in all biografts are formed and boric acid, MgO and SrBr2 additives increase the compressive strength and hardness values
