Abstract. Mechanical properties: The Vickers hardness and bending strength of porous biomorphic SiC (bioSiC) ceramics fabricated from different natural hardwoods were investigated. It has been found that these parameters are highly dependent on the geometrical densities of ceramics, and Vickers hardness values can be well described using the Ryskevitch-type equation. It has been shown that the data of geometrical density bio-SiC ceramics can be used to estimate mechanical parameters such as bending strength. Materials with advanced properties appropriate for surgical applications are being designed. Further ways to improve the mechanical properties of ceramics and ceramic products have been discussed.

“…During the last decade, biomorphic silicon carbide (BioSiC) prepared by Si vapor or by Si-melted reactive infiltration of carbon templates, previously obtained by pyrolysis of different kinds of wood, has received great attention. [126][127][128] The reason for this is not only due to wood's good thermomechanical properties, but also to its large availability, renewability, low cost, and very low environmental impact. 129 The morphological characteristics of BioSiC closely resemble that of the different kinds of wood utilized for its preparation.…”

By mimicking Nature, we can design and synthesize inorganic smart materials that are reactive to biological tissues. These smart materials can be utilized to design innovative thirdgeneration biomaterials, which are able to not only optimize their interaction with biological tissues and environment, but also mimic biogenic materials in their functionalities. The biomedical applications involve increasing the biomimetic levels from chemical composition, structural organization, morphology, mechanical behavior, nanostructure, and bulk and surface chemical-physical properties until the surface becomes bioreactive and stimulates cellular materials. The chemical-physical characteristics of biogenic hydroxyapatites from bone and tooth have been described, in order to point out the elective sides, which are important to reproduce the design of a new biomimetic synthetic hydroxyapatite. This review outlines the evolving applications of biomimetic synthetic calcium phosphates, details the main characteristics of bone and tooth, where the calcium phosphates are present, and discusses the chemical-physical characteristics of biomimetic calcium phosphates, methods of synthesizing them, and some of their biomedical applications.

“…[1][2][3][4][5][6] Previous research [7][8][9] has shown the viability of infiltrating molten metal into the pore space of wood-derived SiC, but characterization of the resulting metal-ceramic composites (MCCs) was limited to room-temperature properties such as compressive strength, modulus, and flexural strength ( f ). The current work aimed to expand on these findings by studying the strength and fracture toughness (K IC ) of MCCs made from various wood precursors as a function of temperature, and to provide a better understanding of the deformation and failure micromechanisms that control their mechanical behavior.…”

The mechanical behavior [i.e., stiffness, strength, and toughness (K IC )] of SiC Al-Si-Mg metal-ceramic composites (50:50 by volume) was studied at temperatures ranging from 25 to 500°C. The SiC phase was derived from wood precursors, which resulted in an interconnected anisotropic ceramic that constrained the pressure melt-infiltrated aluminum alloy. The composites were made using SiC derived from two woods (sapele and beech) and were studied in three orthogonal orientations. The mechanical properties and corresponding deformation micromechanisms were different in the longitudinal (LO) and transverse directions, but the influence of the precursor wood was small. The LO behavior was controlled by the rigid SiC preform and the load transfer from the metal to the ceramic. Moduli in this orientation were lower than the Halpin-Tsai predictions due to the nonlinear and nonparallel nature of the Al-filled pores. The LO K IC agreed with the Ashby model for the K IC contribution of ductile inclusions in a brittle ceramic.
