“…Subsequently the catalyst particles are removed to obtain a monolithic, graphitic carbon material that combines the properties of pyrolysis-derived carbons, such as low density and aligned, hierarchical porosity [32,33] with the properties of graphite, such as high degree of ordering, low thermal expansion and good thermal and electrical conductivities [24] making them ideal candidates for many thermal management applications. Thermal properties of woodderived materials have been reported for ceramics [34], composites [35] and carbons [36].…”

Graphitic porous carbon materials from pyrolysis of wood precursors were obtained by means of a nanosized Fe catalyst, and their microstructure and electrical and thermal transport properties investigated. Thermal and electrical conductivity of graphitized carbon materials increase with the pyrolysis temperature, indicating a relationship between the degree of graphitization and thus in crystallite size with transport properties in the resulting carbon scaffolds. Evaluation of the experimental results indicate that thermal conductivity is mainly through phonons and decreases with the temperature in Fe-catalyzed carbons suggesting that due to defect scattering the mean free path of phonons in the material is small and defect scattering dominates over phonon-phonon interactions in the range from room temperature to 800ºC.

“…[1][2][3] While previous efforts have focused primarily on the development and characterization of biomorphic silicon carbide from wood, [4][5][6][7][8][9][10] biomorphic graphitic scaffolds are of particular interest due to the attractiveness of porous graphite for use in thermal management devices. 11,12 Graphitic scaffolds combine low density, low thermal expansion coefficient, and high thermal conductivity, making them ideal candidates for many thermal management applications.…”

A catalytic technique to enhance graphite formation in nongraphitizing carbons was adapted to work with three-dimensional wood-derived scaffolds. Unlike many synthetic graphite precursors, wood and other cellulosic carbons remain largely disordered after high temperature pyrolysis. Using a nickel nitrate liquid catalyst and controlled pyrolysis conditions, wood-derived scaffolds were produced showing similar graphitic content to traditional pitch-based graphite while retaining the high-aspect ratio pores of the precursor wood microstructure. Graphite formation was studied as a function of processing time and pyrolysis temperature, and the resulting carbons were analyzed using x-ray diffraction, Raman spectroscopy, x-ray photoelectron spectroscopy, and electron microscopy techniques.

“…Further, they measured their mechanical properties [86] as well as load partitioning among the phases using in-situ diffraction experiments [87] and performed detailed investigations on their microstructure by means of x-ray computed micro tomography [52]. Copper-SiC composites have also been fabricated by electroplating targeting thermal applications by Pappacena et al [88,89].…”

In one approach, one selects the main microstructural features responsible for improved properties a designs processes to obtain materials with such microstructures (continuous-fiber-reinforced ceramics, porous ceramics, fibrous ceramic monoliths, etc.). In a different approach, it is possible to use natural materials directly as microstructural templates. Biomorphic ceramics are produced from natural and renewable resources (wood or wood-derived products). A wide variety of SiC based ceramics can be fabricated by infiltration of silicon or silicon alloys into cellulose-derived carbonaceous templates, providing a low-cost route to advanced ceramic materials with near-net shape potential and amenable to rapid prototyping. These materials have tailorable microstructure and properties, and behave like ceramic materials manufactured by advanced ceramic processing approaches. This review aims to be a comprehensive description of the development of bioSiC ceramics:from wood templates and their microstructure to potential applications of bioSiC materials.
