Highlights:• Bone has a complex multi-level hierarchical organisation. This structural organisation is key for its outstanding properties. • Artificial calcium phosphate ceramics (CPCs) are promising for achieving the set of mechanical and biological requirements for use as bone implants. • At individual lengthscales, methods have been developed to control crystal phases, microscale porosity and macroscopic geometry but the CPCs produced remain intrinsically brittle. • Inspired by the organisation of bones and other biomaterials, CPCs and their composites could have their toughness increased through multi-level hierarchical microstructures. • Challenges remain but recent advances in ceramic processing and toughening may pave the way for a new generation of medical implants.

“…Drdlik et al [86] used electrophoretic deposition to prepare HAp/ ZrO 2 microfiber with controlled fracture and microporosity properties. Vickers hardness and elastic modulus of composites enhanced with dispersions milling time prior to electrophoretic deposition and were reduced with the ZrO 2 microfibers amount in the coatings, which is related to the density of composites.…”

“…This result is in good agreement with our 3% increase of the hardness. Generally, the hardness of ceramics is dependent on its porosity and grain size [28,29]. However, the transparent ceramics contain porosity close to zero, so the main parameter influencing its hardness is the grain size.…”

Alumina ceramics found their utilisation in many applications which can be further extend by attaining functional properties; in our case the transparency obtained through precise processing and photoluminescence due to erbium (Er) doping. In order to examine the optical, mechanical and fractographic response of transparent alumina on Er doping, slip casted samples containing 0-0.15 at.% of erbium nano-oxide were pre-sintered by two-step sintering regime and then hot isostatically pressed. Prepared samples exhibited fully dense submicron microstructure and corresponding high transparency (RIT up to 60%). Positive influence of doping on the Vickers hardness resulted in values up to 27 GPa (at 10N load). Moreover, the comparison of the Vickers hardness determined at different loadings with literature data showed that the Er doped alumina is one of the hardest material in this category. The samples were characterised also in terms of fracture toughness and fractographic behaviour.
