Abstract

Field of Research: The present proposal aims to expose the actual interest of the authors on developing a post-doctoral project in the multidisciplinary area of biomaterials, in particular bio-ceramic engineering. Backgrounds: A thorough literature review conducted by the candidate reveals that the fracture toughness of commercial bioactive glass-ceramics (1-2 MPa.m1/2) is still below the desired standards and should be improved to come close to that of human cortical bone (2-12 MPa.m1/2). Additionally, all toughening mechanisms have not been activated in glass-ceramics yet. There are still several toughening routes, such as transformation toughening, bridging, micro cracking and pull out, which can be stimulated by controlled crystallization of different crystals with a variety of morphologies and structures. For instance, chain silicate crystals, such as enstatite, wollastonite, diopside, canasite, etc. have elongated and needle-like morphology that could reinforce glass-ceramics. Furthermore, enstatite undergoes a martensitic transformation from the orthorhombic phase, protoenstatite, to the monoclinic phase, clinoenstatite that develops twinning, which is responsible for unusually high fracture toughness. Glass-ceramics containing such crystals may have higher strength and fracture toughness. General Objective: Therefore, we intend to develop tough bioactive glass-ceramics based on designed microstructures resulting from the internal crystallization of chain-silicate crystals, e.g., enstatite.
